Best Ultralight Rain Jackets
Arc’teryx Alpha SL
The new-for-2026 men’s Arc’teryx Alpha SL Jacket and women’s Arc’tyerx Alpha SL Anorak are the lightest GORE-TEX PRO shells in existence, and the most reliably durable, waterproof breathable ultralight rain jackets that money can buy. Their minimalist features set includes a single large chest pocket, hood and hem cinching, a stiffened brim, and Velcro cuff adjusters. Notably, it does not have pit zips. This is a serious drawback, and the only reason that it ties, rather than surpasses, the other tier 1 options. Those will vent heat better. Nonetheless, if you’re expecting lots of rain, or want your ultralight shell to last as long as possible, we highly recommend Arc’teryx Alpha SL!
- Weight: 8.2 oz jacket | 6.5 oz anorak
- Price: $500 | $450
- Fabric: 20d, GORE-TEX PRO
- Pit Zips: No
- Waterproofness (HH): ~28k*
- Breathability (MVTR): ~25k*
- Pros: Ultralight. Durable and extremely reliably GTX PRO shell waterproofing. 3-layer. Pit zips. Chest Pocket.
- Cons: No pit zips! Heavy-end of ultralight spectrum.
Zpacks Vertice Rain Jacket
Zpacks Vertice meets all of our strict criteria with a sub 6-oz super ultralight weight, 3L fabric composition, and full size pit zips. On top of that, the Vertice membrane is hyper breathable, scoring 56k on MVTR testing, roughly double the breathability of Gore-Tex and eVent. On paper, it is the best performance option currently available; however it’s not without flaw. The 7d fabric is fairly delicate so wearers must treat it with respect. While the unique drawstring wrist straps are lighter and in some ways advantageous, we still prefer Velcro. Perhaps its greatest drawback is the use of old school C6 DWR with PFAS; very effective, but a sustainability no-no.
- Weight: 5.9 oz
- Price: $299
- Fabric: 3L Vertice membrane, 7d face
- Pit Zips: Yes
- Waterproofness (HH): 20k
- Breathability (MVTR): 56k
- Pros: Super ultralight. 3-layer. Pit zips. Hyper breathable. Chest Pocket.
- Cons: Slightly delicate. Drawstring wrist cinch. Eco-unfriendly PFAS DWR.
Montbell Versalite
Montbell Versalite is arguably the most classic ultralight rain jacket of all time, and it just got a big upgrade for fall 2025. The new version is now three layer, and uses Montbell’s proprietary Super Dry-Tec membrane and a 7d face with 53k on breathability instead of WINDSTOPPER. It still has pit zips, but no hand or chest pockets. All in, this is a major upgrade on an already great piece of gear.
- Price: $285
- Weight: 5.9 oz
- Fabric: 3L Super Dry-Tec, 7d face
- Pit Zips: Yes
- Waterproofness (HH): 20k
- Breathability (MVTR): 52k
- Pros: Ultralight. 3-layer Fabric. Very breathable. Pit Zips. Velcro cuffs
- Cons: Slightly delicate. No chest or hand pockets.
Montbell Peak Shell
The Montbell Peak Shell is an essentially flawless ultralight rain jacket made with Gore-TEx, and one of only a select few models offering all three of the most desirable characteristics – 3L fabric, sub 8-oz weight, and pit zips. It’s only downsides are the high price tag, and low baseline breathability of GT fabrics.
- Price: $350
- Weight: 7.0 oz
- Fabric: 3L Gore-Tex, 15d face
- Pit Zips: Yes
- Waterproofness (HH): 20k
- Breathability (MVTR): 20k
- Pros: Ultralight. 3-layer Fabric. Pit Zips. Gore-tex waterproofing. Nice Velcro cuffs.
- Cons: Expensive. No hand pockets. Gore-Tex breathability is below average.
Outdoor Vitals Tushar Rain Jacket
The Outdoor Vitals Tushar Rain Jacket is a rare blend of ultralight weight, pit zips, breathability, smart design, and exceptional bang-for-your-buck, held back from true greatness only by virtue of not being a true three layer fabric. That being said, the 3D printed interior coating mimics the benefits of three layer fabric in a way that feels less plastic-y and more textural against skin, and protects the membrane from abrasions and oil. We love the use of hybrid mapped design, which boosts waterproofness in high exposure/rub areas, and boosts breathability where it’s needed most (front torso, underarms, etc). We’re stoked to get pit zips at this price point, but they are the smallest in our round-up, and we wish they were about 50% longer. Read more in our Outdoor Vitals Tushar Rain Jacket Review.
- Weight: 7.4 oz
- Price: $225
- Fabric: 2.5L Toray Torain 3D
- Pit Zips: Yes
- Waterproofness (HH): 29k hood, shoulders, back | 16k torso, underarms
- Breathability (MVTR): 20k hood, shoulders, back | 29k torso, underarms
- Pros: Ultralight. Pit zips. Great value. Hybrid-mapped. 3D-printed interior texture mimics the benefits of 3L fabric.
- Cons: Not quite 3L, still kind of plastic-y. Unisex sizing only. No hood adjustment. Pit zips are small.
The North Face Summit Series FUTURELITE Papsura Jacket
The new-for-2025 The North Face Summit Series FUTURELIGHT Papsura Jacket is a true 3-layer ultralight minimalist rain shell, weighing in at just eight ounces; a shocker considering how far TNF has drifted away from technical and towards gorpcore. While the 3L composition and ultralight weight place it into an elite grouping, it’s held back from a gold medal award due to the lack of pit zips. Its hand pockets are a nice touch for hanging around at camp, but we would have traded them for a chest pocket to save weight or bumped higher up the torso for use while wearing a hip belt. See more in our full length The North Face Papsura Jacket Review.
- Weight: 7.9 oz
- Price: $390
- Fabric: 3L FUTURELITE, 15d Face
- Pit Zips: No
- Waterproofness (HH): Not Provided
- Breathability (MVTR): Not Provided, (FUTURELIGHT was 75k in 2019)
- Pros: 3-Layer. Ultralight. Hand pockets. Use of recycled fabrics and PFAS-free DWR. Toothed zipper.
- Cons: No pit zips! Hand pockets are not optimized for hip belt use. WP/B stats not provided.
Patagonia Storm Racer
The Patagonia Storm Racer is a minimalist ultralight rain jacket designed for trail running, but perfectly suited to hiking, thanks to its low weight and three layer composition. This is an extremely minimalist design with its only feature being a chest pocket; the lack of pit zips are its greatest drawback. Patagonia is always notable for sustainability, and we’re pleased to see the use of 100% recycled fabric and PFAS-free DWR (in addition to their non-profit ownership and 1% for the planet. We find the fit of Storm Racer to run trim, so size up if in between.
- Weight: 7.2 oz
- Price: $315
- Fabric: 3L H2No, 20d face
- Pit Zips: No
- Waterproofness (HH): 20k (to meet Patagonia standards)
- Breathability (MVTR): Not provided
- Pros: Ultralight. 3-Layer. Chest pocket. Use of recycled fabrics and PFAS-free DWR.
- Cons: No pit zips! Trim fit. WP/B stats not provided.
La Sportiva Aequilibrium Lite GTX
The La Sportiva Aequilibrium Lite GTX is a superb ultralight Gore-tex rain jacket held back from true greatness only by lack of pit zips. But beyond that, it meets all our other strict criteria, including 3L fabric, and a sub-8-oz total weight. Features include a chest pocket and hood cinch which we like. However, one minor flaw worth calling out is how the elasticized fabric bands on hem and cuff are not protected by a fold over layer of waterproof fabric, exposing them to unnecessary moisture which will result in damp edges. Nonetheless, very few Gore-tex jackets come in under eight ounces, which makes Aequilibrium Lite highly coveted and very effective.
- Weight: 6.8 oz
- Price: $309
- Fabric: 3L Gore-Tex
- Pit Zips: No
- Waterproofness (HH): 28k
- Breathability (MVTR): 20k
- Pros: Ultralight. Gore-Tex. Chest pocket.
- Cons: No pit zips. Unprotected elastic at cuff and hem will absorb water.
Stellar Equipment Ultralight Shell 2.0
Stellar Equipment Ultralight Shell Jacket 2.0 is the first Toray Dermizax membrane we’ve tested, and early experiences have proven positive. This lightly stretchy, 3L Gore-Tex alternative works by using a non-porous, hydrophilic membrane that transports warm interior moisture build up through a chemical process, rather than relying on microscopic holes. Beyond that, it’s another minimalist ultralight rain jacket with a single chest pocket, hood perimeter adjusting, and elasticized cuffs and hem. The 20d face is heavier duty than we normally prefer, but a worthy choice if you want something lightweight, stretchy, and reasonably durable.
- Weight: 8.4 oz
- Price: $349
- Fabric: 3L Toray Dermizax, 20d face
- Pit Zips: No
- Waterproofness (HH): 20k
- Breathability (MVTR): 20k
- Pros: Ultralight. Toothed zipper. Lightly stretchy.
- Cons: No pit zips. No crown adjustment. Trim fit size up. Half ounce heavier than ultralight benchmark.
Mammut Aenergy TL HS
Mammut Aenergry TL HS (three layer hard shell) is your quintessential ultralight rain jacket for a very reasonable price. Its 3L Pertex Shield fabric scores an industry standard 20k/20k on WP/B testing, while hitting the bullseye on target weight – just six ounces for a trim men’s medium. Its lightly stretchy fabric accommodates movement well, and the elongated upper cuffs do a good job keeping wrists dry, even as sleeves get tugged. Had the designers added pit zips, it would be competing for the podium. But as-is, Aenergy earns our seal of approval, and a solid mid-pack finish when competing against the other best ultralight rain jackets in the world.
- Weight: 6.0 oz
- Price: $269
- Fabric: 3L Pertex Shield, 20d face
- Pit Zips: No
- Waterproofness (HH): 20k
- Breathability (MVTR): 20k
- Pros: Ultralight. Lightly stretchy. Good cuffs.
- Cons: No pit zips. Runs small, size up. Non-waterproof zipper track.
Mammut Eiger Nordwand Light HS
The Mammut Eiger Nordwand Light HS is one of a select few ultralight Gore-Tex rain jackets available, all of which are worth considering. Designed for mountaineering but just as well-suited to the trail, Eiger Nordwand Light delivers exceptional waterproofness, good durability, a toothed zipper, elasticized hem and cuffs, single chest pocket, and a generous crown adjuster. We love the long torso length which creates a generous rain seal with your shell pants. Fit is euro trim, so consider sizing up.
- Weight: 8.3 oz
- Price: $399
- Fabric: 3L GORE-TEX, 15d face
- Pit Zips: No
- Waterproofness (HH): 28k
- Breathability (MVTR): 20k
- Pros: Ultralight. Toothed zipper. Great waterproofness. Long drape.
- Cons: No pit zips. Trim fit. Heavy end of ultralight.
Outdoor Research Helium UL
Outdoor Research Helium UL is the fourth edition of the brand’s flagship ultralight rain jacket, and the best version yet thanks to the introduction of Toray Dermizax. This Japanese membrane tech scores a respectable 20k/20k on waterproof/breathability testing, and is encased in a 2.75 layer sandwich of 15d ripstop nylon, and a 3D interior layer. The latter is more protective and less fabric-y than traditional 2.0L or 2.5L membranes, but not quite as nice as true 3L. Features include a hood and hem cinch; single chest pocket for men or dual hand pockets for women; brim stiffer; and elasticized hood, cuff, and hem openings.
- Weight: 5.7 oz
- Price: $225
- Fabric: 2.75L Dermizax, 15d
- Pit Zips: No
- Waterproofness (HH): 20k
- Breathability (MVTR): 20k
- Pros: Ultralight. Good value. Brim stiffener. Less plastic-y inner texture.
- Cons: No pit zips! Not quite 3L, still kind of plastic-y.
Path Projects Stratus
Designed for running but great for hiking too, the Path Projects Stratus weighs just 6.3 oz, and is built with a Toray Dermizax fabric scoring a respectable 20k/20k on waterproof breathability. The 2.75L interior face fabric isn’t quite as good as true 3L, but does a solid impression. Compared to classic 2.5L, it’s a clear upgrade and feels more durable and less plastic-y against skin. The chassis of this minimalist jacket features Velcro cuffs, hood and hem cinching, and a small side pocket. Pit zips would have been a huge upgrade, especially for runners. But all in, this is still a very respectable ultralight rain jacket for a very respectable price.
- Weight: 6.3 oz
- Price: $248
- Fabric: 2.75L Dermizax, ~10d
- Pit Zips: No
- Waterproofness (HH): 20k
- Breathability (MVTR): 20k
- Pros: Ultralight. Good value. Veclro Cuffs. Less plastic-y inner texture.
- Cons: No pit zips! Not quite 3L, still kind of plastic-y. Men’s sizes only. Unusual pocket placement.
Lightheart Gear Rain Jacket
For an ultralight rain jacket that is 100% waterproof and never wets out, choose Lightheart Gear. But to immediately clarify, this fabric has literal zero breathability because it’s coated in silicone and polyurethane (like a tent fly). Lightheart’s theory is that even the most breathable rain jackets are still clammy and mechanical vents (a la its large pit zips) do a better job of keeping the wearer cool; so why not forgo a membrane altogether? We only kind of agree with this concept, but certainly respect the bold design choice to forgo WP/B technology, which in turn reduces price. A few other things we like about this jacket are its large hood brim, and toothed zipper.
- Weight: 7.4
- Price: $150
- Fabric: 1L Sil/PU polyester, 20d (basically a tent fly)
- Pit Zips: Yes
- Waterproofness (HH): 5k*
- Breathability (MVTR): 0
- Pros: Ultralight. Massive pit zips. Most waterproof, never wets out. Great value. Nice hood brim. Toothed zipper. Hand pockets.
- Cons: Zero breathability. Not 3L! – 1L fabric is plastic-y and unpleasant against skin.
*Despite being one of the most waterproof rain jackets in practice, due to the workings of hydrostatic head testing, it scores lower than membrane-based fabrics.
Essential Information For Understanding Your Rain Jacket

Learn, how and why rain jackets fail.
In this guide, we give you critical information you won’t get elsewhere to help you understand important features for ultralight rain jacket performance. We dive into breathability, durability, waterproof/breathable (WP/B) fabric technologies, etc. And dispel a few myths, like wetted out jackets do not breathe (they do!), etc.

Understanding Breathability
Or why waterproof-breathable rain jackets get an unfair bad rap for not being breathable enough
The truth is, that when exercising hard, you’ll get significantly wet-from-the-inside wearing ANY wind-resistant jacket or shell—even a light supposedly “breathable” wind shirt! Put the fabric up to your mouth. If you can’t easily breathe through it then it will trap a lot of moisture, even if it is non-waterproof wind shirt.
The problem has more to do with having any wind-resistant fabric covering you than whether it’s a plain “breathable” nylon fabric, or a waterproof-breathable fabric for a rain jacket. And the difference in wetness-from-the-inside for a wind shirt vs. waterproof/breathable rain jacket may be less than you think.
Why any shell increases moisture retention
Any wind-resistant shell, hiking rain jacket or wind shirt, blocks air movement to and from your base layer and the outside environment. This has the following consequences:
- The shell retains heat, trapping warm air against your skin, and making you significantly warmer and sweat more. (In technical terms your shell creates a “boundary layer” of non-moving moist air.)
- Moist air from your skin/base-layer can’t move freely to drier and possibly cooler outside air (as it would if you were just wearing a T-shirt exposed to the outside air). This essentially traps most of your body moisture inside the shell —thus the term wet-from-the inside.
From the above, you can see why even a “breathable,” non-waterproof wind shirt can cause moisture to build up rapidly. And the harder you exercise, the worse it gets. This is supported by a lot of research by the Armed forces clothing test labs and other PhD professionals in the field. And I did some controlled testing with runs in both a wind shirt and a WP/B rain jacket. In an hour the rain jacket only accumulated 20% more sweat on my base-layer.
Rainwear gets a bad rapport
All shells retain warm moist air and tend to get an unwarranted bad rap for not being breathable. Or at least people should also start complaining about how unbreathable wind shirts are.
This is the reason I no longer carry a wind shirt. Instead, many times I use a fleece shirt/jacket for warmth in moderate wind. While nowhere near windproof, it does a decent job of blocking enough of the wind to keep me warm. The benefit is that I don’t end up getting sweaty chilled out.
Finally, when it does get cold enough and/or windy enough to chill me, I use my rain jacket as a “wind-shell.” By this point it’s cold enough that moisture accumulation in the rain jacket is not a big a deal.
When to Consider a Soft Shell Jacket
Ultralight softshell jackets, like the Patagonia Houdini, are sometimes a better choice. And if you want a packable rain jacket, you will love a windbreaker. That’s because you don’t always need a waterproof hiking rain jacket. The Houdini Air is a great choice for day hikes and trail runs where there may be a chance of rain, snow, or high winds. It is not waterproof and will not keep you dry in any excess moisture, but it’s a way more efficient, light, and affordable “just in case” layer than a fully waterproof rain jacket.
The fabric does still have a DWR finish so it will repel light moisture, and it also dries extremely quickly if it gets any sweat build-up. We don’t recommend taking the Houdini as your only rain layer on something like a thru-hike or a backpacking trip with sure rain in the forecast, but it’s a great additional layer to add for shorter trips. However, we would not recommend that as a backpacking rain jacket.
How And Why A Lightweight Rain Jacket Fails – 3 Elements of Durability
A. Outer shell fabric durability
The ability of the rainwear’s exterior fabric to:
- Resist tearing, punctures and abrasion damage. Most ultralight rain jackets struggle with this, which is we like the durable, 6.4 oz Helium Rain Jacket so much.
- Maintain its water shedding & breathability—usually with a durable, water repellent finish DWR
Note: outer shell fabric “wet out,” the breakdown of this water shedding property, does not completely stop all breathability as is popularly believed. See more below.
B. Inner waterproof/breathable (WPB) membrane durability
The ability of a lightweight rain jacket WPB lining to maintain waterproofness AND breathability:
- The WPB membrane should remain physically intact under the wear and tear of garment use (not so easy in regular use with a backpack!).
- In particular the WPB membrane should not delaminate from the outer shell, develop cracks, etc. In this case, 3-layer construction jackets are likely more durable. That’s because their inner fabric liner protects the more delicate WPB membrane vs. the unprotected membrane of 2.5 layer jackets.
- The WPB membrane should not foul with body oils, dirt, detergent residues or other materials which will cause the WPB membrane to leak.
C. Hardware failures
- Zippers that jam, no longer mate at the bottom, or start auto-separating in the field
- Elastic adjusters on hoods, cuffs and hems of jackets. Velcro that looses its stick, adjusters/buckles that break or slip, etc.
So What Fails Most Often?
[Two high quality 2.5 layer backpacking rain jackets from big name outdoor gear companies] In my experience, membrane delamination like this in the neck and upper shoulders is the most common way that rainwear permanently fails. While this happens faster to the unprotected WPB membrane of 2.5-layer jackets like these — if you wear a 3-layer jacket long enough it too will eventually delaminate and leak. And backpackers beware: wearing a pack dramatically speeds up this delimitation process for both 2.5 and 3-layer jackets!
1) Waterproof Breathable Membrane Delamination
As the pictures above show, WPB membrane failure is likely the first and most common, the non-fixable way ultralight rain jackets fail (leak). And note that while the examples are dramatic, many small cracks, punctures, and delaminations are not obvious but will still cause your jacket to leak. This is true for 2.5 and 3-layer jackets, although a 3-layer lightweight rain jacket will usually last longer.
This is one reason why the outdoor industry still makes a big deal about 2.5 vs 3-layer construction.
Note: Many outdoor companies like Patagonia, REI, and Outdoor Research, offer good product warranties that cover zipper failures, membrane delamination, etc. This will protect your jacket as a long term investment. But if your jacket fails in the field you may have to suffer through wet until you get home and can ship it back for repair or replacement.
2) “Wet Out” (DWR failure) – Outer Shell no Longer Beading/Shedding Water
Fabric ‘wet out’ reduces but doesn’t completely stop breathability. [click photo to enlarge]
Wet out is another common “failure,” altho it can be fixed. Wet out happens when the durable, water repellent finish DWR no longer beads up and sheds water. The most common reason for this is the DWR finish (a chemical) wearing off after many garment washings, and/or the surface getting fouled with dirt and other compounds. While this doesn’t cause the rain jacket to leak, it does likely slow down the breathability of the jacket (see more below). This makes it easier to sweat out the inside of the jacket if you are working hard. Your DWR can be refreshed by washing the jacket and treating it with a DWR restoring wash compound and/or spray. E.g. some of these from Nikwax.
Note: While some newer fabrics like Columbia OutDry Ex Eco are inherently hydrophobic and don’t need a DWR. You will still need to keep the fabric free of dirt for the best water shedding.
Myth: A Wetted Out Rain Jacket Doesn’t Breathe
It’s a myth rainwear stops breathing once it wets out. This is according to interviews I had with 1) Jeff Mergy, the Director of the Innovation Team at Columbia Sportswear (among other things tech. guy for OutDry Ex Eco Fabric and 2) Dr. Fred Wilson PhD a long term industry scientist who worked for both GORE and eVENT on WPB fabrics.
In an interview I had with Jeff Mergy, he stated that WPB membranes are still breathable when the outer shell is wetted out but not as breathable. It is still not clearly understood how less breathable but Jeff believes it is significant. BUT he said that part of what consumers believe is “not-breathable” is often the clammy next skin feel of conventional WPB jackets. Water shedding fabrics like OutDry and FutureLight help with this by having an actual wicking fabric that feels far more comfortable next to the skin. Even when the outer shell is wetted out. [Note: other 3-layer technologies with a fabric liner should have a similar non-clammy feel.]

I’d like to toss out Janji Rainrunner as an option to try. I got lucky purchasing mine 3 years ago, clearance rack at REI for $50. Didn’t know anything about it at the time, just looked like a lightweight rain jacket to replace my Torrentshell. Its performed perfectly. Never wets out, vents a lot better than pit zips, used it several times as a shell in single digit tempatures, and while I don’t think it’s the most durable it hasn’t ripped or shown signs of wear (and that’s with a lot of rock scrambling wearing it).
Thanks for the suggestion! It fits the bill on specs, but I’m hesitant about back vents because they have an unreliable interaction with backpacks. Depending on the configuration of pack and wearer’s body, the pack might pull the vent open, or gradually abrade it. Great for running, but I can’t broadly recommend it for hiking because results are variable.
Thanks for writing this. I love that these jackets are so very light. It’s personally am very interested in the LightHearted gear and applaud them for using fabric with zero breathability, because in actual use, that is exactly what Gore Tex is.
I have owned at least 4 Goretex jackets over the years; my last two from Arcteryx. My biggest gripe is they do not breathe….at all. I don’t ask much from these jackets. I only use them on hikes…no pack carrying while wearing them usually. Unless they have pit zips (which my latest does not) they will not breathe, even for just walking around.
My second gripe is they do not last very long. Two of my 4 Gore tex jackets delaminated. I am confident the one I sold delaminated eventually for the second owner, and I am equally confident my current Arcteryx will delaminate in a few years (it was a warranty replacement, so the price was right.) My $500+ Arcteryx Theta AR spent most of its life in my closet, yet it delaminated in about 10 years. Yes, that’s a long time, but not for how little I used it. I will say Arcteryx stands behind their stuff!
My 3rd gripe with Gore Tex is the price. If not for my first two gripes, I would happily pay the price. Sadly this is not the case.
Why pay the price for an expensive membrane if it doesn’t really breathe.
You’re definitely right that waterproof breathable jackets never breath as well as expected, and always fail eventually, and that the Lightheart Gear rainwear eliminates both of those major problems. I think the Lightheart is incredible for its bold simplicity and admission of some core problems that all other jackets face. But when a WP/B is in good shape, clean, fresh DWR, and you don’t totally overwhelm it with body heat, the primo options are notably comfier than a non-breathable sil-nylon.
One note about the lightheart gear silpoly jacket. I have only used mine a couple of times, over the years, but sadly, the PU coating on the inside of the silpoly version is now delaminating. I should have gotten the silnylon version.
Just got my vertice in the mail today and it’s a total POS. Literally falling apart out of the package. Front zipper doesn’t stay closed, hood and sleeve pulls falling off. Did I just get a dud? Debating asking for an exchange or a refund. Looks like the Visp is discontinued.
Dang sorry to hear that! Obviously, the Vertices Alan and I have used were in good working order. You should 100% ask them for a return/exchange. Visp is termporarily discontinued while EE sources a new fabric. Word on the street was the mill that made it went under. If you’re not into Vertice and Visp is still gone, go for the Montbell
Have you tried the Montbell SUPER DRY-TEC PEAK SHELL JACKET? How does it compare to the Montbell Versalite? I’m curious how the lighter weight 3 layer is compared to the Versalite, with comfort and durability.
Have not! but looks really sweet, and better than Versalite in theory because 3L is basically always preferable. Will have to check that one out. Likely comfier. The 7d face fabric is going to be less durable than versalite which is 10d, but the inside face of Super dry tec having a third layer (comp to versalite being 2L) increases durability as well. Thanks for the tip. If you get one let us know what you think.
Looks like Versalite is now super dry tec, 3L, 7D, and increased breathability.
Wow, that’s a nice upgrade! I’ll have to check out the new version – thanks for the tip off.
Please get the OR Helium off this list. LOL. I can’t find a single person who has stayed dry in that jacket. It’s a flawed jacket. It wets through in minutes, in the very environment you recommend it for: mid afternoon summer thunderstorms.
What’s the difference, pluses and mines to compare two highly rated of rain jackets- Montbell STORM CRUISER JACKET and Arc’teryx Beta LT Jacket?
Hi Ramona,
Both great jackets, of course. And with similar 3L Gore-Tex chassis, similar pocket configuration, and similar pit zips. The Beta LT is going to be more durable (2x the denier) and a few ounces heavier, with a slightly roomier fit. The Storm Cruiser is going to be a few ounces lighter weight, and a bit trimmer. Neither is strictly better than the other. Storm Cruiser would be favorable from an ultralight perspective, Beta LT would be favorable from a durability/protection/longevity perspective.
Thank you very much for your response. Very helpful. Thank you for your work and this blog.
I would like to see LightHeart Gear and Columbia Outdry Extreme reviewed.
According to Skurka’s Alumni Group these two were the top performers on this year’s apparently pretty wet Alaska Brooks Range Exhibitions
Hi Gerry,
Thanks for the feedback. Both of those jackets are known to us, and both get a thumbs up and make extra sense for Alaska specifically. That’s because they both absorb no water, extended periods of drenching rain is more likely, and the climate is overall cooler so you’re less prone to sweating, thus less prone to needing a super high breathability jacket like the Enlightened Equipment Visp (The Lightheart fabric has literal zero breathability, relying completely on pit zips). We’ll see about revisiting them!
LightHeart Gear 20D ripstop polyester jacket. Truly waterproof and has excellent venting. Much lower price too.
Montbell Storm Cruiser looks outstanding as compare to all other jackets. Its a breathable and fully water proof jacket. I like its color and price is reasonable.
Do you know of a rain jacket or coat that has a clear face shield/mask? I saw someone with one walking the streets of NYC last week and thought it was perfect!
Hi Anne, sorry but I don’t know of a rain jacket or coat that has a clear face shield/mask. For the most part since backpacking and hiking are moderately aerobic, I am fairly sure that such a face mask would turn the entire hood of the jacket into a foggy steam bath. Seems more of a feature for standing still or going a few city blocks than for a long hike outdoors. Best, -alan
Hello. I own a Marmot Precip and it’s fine for warmer temperatures. I’d like to get a Gore-tex, or fabric that does the same thing, rain jacket that has a real zipper. Those water proof zippers without the flap, like the OR Foray has, are too much risk on CT hikes for my taste. What do you suggest?
Hi Wayne, nice to hear from you. The industry consensus seems to be that a waterproof zipper (really highly water resistant) with a backing flap works well, saves the weight of an external flap and the bother securing and un-securing that flap with velcro or snaps. Thus, external zipper flaps are rapidly disappearing from much of backpacking gear — even on tents. My experience is they work better than a standard non-waterproof zipper with an external storm flap and are far less fussy to use. So I would suggest you put zipper configuration aside and pick a jacket from the category that meets your needs needs and your budget. If you would like a suggestion(s) for a particular category I would be happy to help. Wishing you warm and dry hiking. Best, -alan
Thanks. I bought a Marmot Spire with the flap. Several co-workers have broken waterproof zippers making the jackets near useless. As an experienced backpacker I’ve learned some things are getting too light. Some even too small, try operating a small PLD with cold hands.
Glad you found a jacket that works for you. Best, -alan
Alan love your site, thank you, it’s a fantastic resource I share with friends. Quick question re sizing – how do you size your rain gear? I’m typically wearing a thin baselayer, 100 weight fleece midlayer hoody (microfleece or R1 Hoody) plus a light 3 oz wind shirt – those layers take up little space. I’m also carrying a puffy down or synthetic jacket as my main insulation layer, which I throw on at rest stops and in camp. In winter my down parka has 7 oz 800fp down and lofts quite a bit. Do you size your rain jacket a full size up to size over your down/synthetic puffy layer for max warmth and down protection? Or do you keep your rain shell closer to body size and size your puffy layer to go over your rain shell and all layers under it?
Ethan, the safest answer is go large. This is especially true if you want to wear your rain jacket to protect a fluffy down jacket (e.g. in Patagonia). In warmer, let wet climates you might want to go more true to size and have the rain jacket perhaps be a bit snug over your down jacket since using since it’s not likely you’ll use it that way often if at all. Hope this helps, best, -alan
FYI, you can buy Montbell products directly from their Japanese website for a whole lot less than their US website. For example, the Torrent Flier currently costs $192.50 delivered to the US vs. $289.00 delivered from the US website. However, the sizing is smaller so the Japanese XL is equivalent to the US Large. If you need a US Size XL you would need to buy it from the US site.
I meant to say the Storm Cruiser, not the Torrent Flier.
Thanks Gerry, that’s good to know. I’ll have to check it out. Best, -alan
Alan,
As usual another comprehensive and extremely useful gear write-up. My one question is why didnt you include the cottage silnylon jackets? A lot of UL hikers use them, and while perhaps not ideal they are light, moderate cost, and in many of our packs. My personal experience with these is that they perform much like a single-wall tent. No outside precip can get in, but also zero breathability so you rely entirely on mechanical ventilation. No matter the temps I always have some superficial wetness on my mid-layer from condensation.
Micah, good Q. When writing a round-up like this there is always question of how many jackets to review and of what type. Too many jackets overwhelms readers with choices. And iot means I haven’t done a good job of filtering them down to a manage set of the best. As such, I have tried to do a good (but not comprehensive) selection of what I deem to be great jackets in every category. AND to select jackets that I think most readers would have interest in. I think it is the latter criteria that put non-breathable jackets in the fringe territory for the vast majority of readers. In skilled/experienced hands, and for those willing to make some compromises they still likely have a role in dry climates with brief and intermittent rain. But with advent of very light breathable jackets in the same weight rainge, the are not likely to be an option for 99.9% of backpackers. But
I was told by an REI employee that the 2 ply fabrics delaminate over time just from temperature fluctuations. I keep mine in the fridge now between excursions.
Mary, delamination is a complex process and temperature and humidity changes might play a minor role. But the major contributor is going to be flexing and abrasion on the inside of the jacket in the neck and shoulder areas where the backpack straps are. That is the more use under a backpack it gets the sooner it will delaminate. I would suggest that storing your jacket in a cool dry place would be fine and free up some space in your fridge. All the best, -alan
I’d like your opinion on the breathability of the Realm vs HMG’s Shell. Even more than g/m2 vapor transfer, I can actually cup my lips on the fabric of the Realm and blow air (with effort) through. Can this be done with HMG’s Shell?
Your review of The Shell doesn’t mention the lack of DWR. Does The Shell’s fabric truly get water to bead off without a DWR, and does this compare favorably against the Realm’s resistance to wetting out? Any idea how The Shell’s lack of need for a DWR compares to some of the membrane-on-the-outside jackets like the Arc’teryx Norvan SL or Outdry Extreme?
Thanks for all you do!
Brian, the HMG shell is definitely less air permeable. I can barely eek a bit of air through it. In comparison I get a lot of air through my Realm.
As to DWR, I really hadn’t bother to notice it on the HMG other than it’s not seemed too clammy when I’ve used it. Altho I always use a long sleeve, wool base layer with any rain jacket. And when it was raining it was generally a serious storm that had my attention elsewhere :-)
I can say that after wearing the Realm for days and days in Patagonia that it is pretty dang awesome and comfortable jacket. Perfect for that scenario. And chest pockets are fab.
The HMG jacket is for an entirely different scenario — good rain protection for intermittent use. and sub 6 oz. For that purpose it does very well. So… ideally like me, you would have the two jackets and pick one depending on the Wx forecast for the trip. Warmest, -alan
