Forget synthetics! Down rocks. A lightweight down jacket is the most weight and cost effective way to stay warm. Lightweight down jackets are less expensive than synthetics,* they weigh less, but most importantly they are so much warmer! It is true that down jackets may be one of the most expensive items in your kit. BUT, if you want to stay warm and happy, nothing else comes close.
|Nov 21 2017: Just added a down jacket that blow the hubcaps off of previous ultralight contenders! It’s the puffiest most insane Michelin Man look of ultralight down jackets. The GooseFeet Gear – 1/2 zip Custom Jacket: At only 9 oz, and with 61% down, this jacket trounces former top warmth-to-weight efficient ultralight down jackets like the Mountain Hardware Ghost Whisperer.|

Debunking a Few Myths About Down Jackets
- Don’t believe the dire warnings about getting down wet—it’s hard to do. In over 40 years of backpacking all over the world in all conditions, I have yet to get my down so wet that it didn’t do a good job of keeping me warm. New water resistant shell fabrics and water resistant down only improve your odds.
- And make no mistake, a wet synthetic jacket is no joy! Keeping your jacket (down or synthetic) dry in the first place, is a better strategy. (See more on this below)
- *Down is the better long term value for staying warm. The only advantage to synthetics is the price. From there it’s downhill. I find synthetics usually lose loft after less than a season of use. This makes them a poor long term value. A good down jacket can easily last you 5 to 10 years.
Go for Down – Skip the extra shirts, pants, and base-layers
If you really want to be warm, Lightweight Down Jackets are where it’s at. That is, your money and gear weight is better spent investing in a warmer down jacket—or even down pants, down hat and down booties. All are far warmer per ounce than extra shirts, pants, and base-layers. You’ll be warmer, pack lighter and save money in the long run.
What’s in this Guide
I own, or have extensively field tested the vast majority of the jackets (and pants) below.
- Down Jackets
- Down Pants and Down Booties
- Note1: All garments below use Ethically Sourced Down (or something very close to it)
- Note 2: We only include garments where the manufacturer provides oz. of down fill. Unfortunately, some major mfrs have stopped providing oz of down fill even upon request—essentially stating “trust us, it’s warm enough.” We are from Missouri…

Note: MyTrail Co. is going out of business — great deals while stock lasts!
* NOTE: “down volume in liters” is a rough approximation of jacket warmth. See more on this below.
The table above gives you a lot of ways to look at down jackets and their specifications since different aspects are important to different people. E.g. someone may be interested in getting the best value down jacket, while another is looking to get an ultra warm jacket for a cold trip.
- What’s the lightest?
- * What’s the warmest? Use “down volume in liters” as a measure of warmth. While “down volume in liters” is the most significant factor, there are other factors that contribute to warmth. A such, down volume is only a crude approximation/starting point for warmth. [Down volume in liters = 0z-down x fill-power-of the-down x 0.016 liter/in3]
- What’s the warmest for its weight? Take a look at “% down” and “down vol. to weight”
- What’s a good value? Take a look at “price,” when compared to “down volume in liters.” And finally, look at “down vol. to price,” which is a crude approximation of the warmth per dollar.
- How durable is it? All of these jackets are fine for use around camp and for rest stops. But note that jackets with 10D or below “shell fabric” should be treated with extreme care. These might not be good candidates for bushwhacking.
Introducing the Lightweight Down Jackets
|new GooseFeet Gear – Custom Down Jacket – $330 (as shown)|
The new warmth to weight king. At 61% down for its weight, the GooseFeet Gear Jacket trounces former top warmth-to-weight efficient ultralight down jackets like the Mountain Hardware Ghost Whisperer or Montbell Mirage. Pictured is a custom 1/2 zip jacket made for me by Ben at Goose Feet Gear. Weight is 9 oz with 5.5 oz of 950 fill power down. It has a deep kangaroo pocket that is great for warming hands and has shopping basket size room for storing stuff in camp.
This is custom work so expect 6 weeks or so wait time. The upside is you get exactly the size and features you want! Note: that I purchased this jacket with my own funds and receive no commissions from sales.
|new MyTrail 850 Fill Hyperlight Hooded Jacket – $249|
Going out of business great deals while stock lasts!
At 44% down for its weight, it’s second only to the GooseFeet Gear Jacket for warmth to weight. The MyTrail HL Hooded is one of the best values in a super warm, fully featured UL down jacket. At 10.5 oz it’s light for its warmth with a generous 4.6 oz of 850-fill-power down. But best of all, it costs significantly less than jackets of similar warmth and you can get it on the shelf.
Pedigree: This jacket was designed by Demetri Coupounas (Coup) founder/owner of GoLite, creator of the legendary GoLite Bitterroot down jacket, likely the best, high performance UL down jackets of its time. And until the closing of GoLite it was the best value on the market! And while the MyTrail 850 Fill Hyperlight is short of the amazing loft of the Bitterroot, it’s still a super warm and light jacket.
|Feathered Friends Eos Down Jacket – $290|
This is Feathered Friends’ lightest weight down jacket, but don’t let that fool you. Though this clocks in at only 10.6 oz, it has 3.7 oz of 900+ fill goose down. That’s more than 30% more down fill than the popular, but more expensive Mountain Hardware Ghost Whisperer. More down fill means more warmth! With a hood, and sinchable waist, this jacket can tighten down to keep all your precious heat in if things get cooler than expected, but the jacket is light enough to take with you on any 3-season outing. There are Men’s and Women’s versions, and as with all Feathered Friends’ goods, it’s made in Seattle, USA.
|Mountain Hardware Ghost Whisperer Hooded – $350|
Mountain Hardwear touts the 7.7 oz Ghost Whisperer as “the world’s lightest full-featured down jacket.” For 1.2 oz more than the Montbell EX Light Down Anorak you get a full front zipper and pockets. MH uses a unique “Whisperer 7D x 10D Ripstop” fabric that is light, tough, down proof, and fairly water resistant. Oh, and the Mountain Hardware Ghost Whisperer has won a ton of awards.
|new My Trail Co – Men’s 800 Fill Ultralight Hooded Down Jacketd Down Jacket – $149|
Going out of business great deals while stock lasts!
New this year or possibly an improved version of the the “Down Light Hooded Jacket.” Either way it’s filled with a generous 5.1 oz of 800 fill power down (up 1.5 oz!) but at 12. 5 oz, weighs less. At 40% down for its weight the this jacket is close on the heels of its more expensive brother the 850 Fill Hyperlight Hooded Jacket. Best of all, like other MyTrail products it costs significantly less than jackets of similar warmth.
|Montbell EX Light Down Anorak – $269|
At only 6 oz, this is about as light and as WARM as it gets! The Ex Light Down Anorak is 2 oz lighter than the highly regarded and more expensive Mountain Hardware Ghost Whisperer. It achieves this low weight in part by not using a full zipper. Instead, you get a hood and a kangaroo pouch pocket! These great pockets let you really keep your hands warm by putting them in the same space against your abdomen. Truly lightweight warmth, this is a perfect puffy layer to bring on high alpine adventures like the South Sierra High Route, or Wind River High Route. The only downside is that there isn’t a Women’s version yet.
|Montbell Mirage Parka – $379|
Weighing less than 14 oz, this is the lightest fully-baffled (a warmer but more expensive construction method) jacket we know of. Montbell has pulled this feat off by using 900-fill down and a very thin 7-denier ballistic nylon shell. Down accounts for over 40% of the garment weight—an incredible feat of design engineering! If you like to bushwhack through dense evergreens, this might not be durable enough for you, but for most backpackers, this will allow pushing shoulder season or even through winters in much of the country (although you may need more in the deep north, see the Helios below). Unfortunately, this jacket doesn’t come in a Women’s version.
|Feathered Friends Helios Hooded Down Jacket – $340|
If you need ultra warmth, this is the jacket for you! The Helios jacket is insane puffy and warm with 3x the down (warmth) of the lightest jackets here.
The Helios packs 2 oz. of high-fill down over the Mirage, and uses a more durable outer fabric. (It also weighs 4 oz more.) It’s made in the USA, and is purpose built with mountaineering in mind, so you know it’s warm! Feathered Friends is known for their high quality down and weight-conscious products.
| REI Co-Op Down Jacket – $99|
If you don’t want to spend a lot of money on a down jacket, REI has you covered. Their Co-Op Down Jacket weighs in at only 10.2 oz (in a non-hooded version). And while the jacket sets no records for warmth to weight ratios with 650 fill power down, it likely has enough warmth for most 3-season purposes. It comes in Men’s, Women’s, and children’s cuts. If you have an extra $20 to spend, we recommend the hooded version, because all jackets are substantially warmer with one!
Tip – Keeping your Lightweight Down Jacket Dry
The best way to keep your gear dry is not to get it wet in the first place. This means keeping the gear in your pack dry (especially your down sleeping bag, and down jacket).
- Pack contents dry: A trash compactor bag inside your pack is lighter and works considerably better than a pack rain-cover. Inside that, put your down bag and down jacket in their own waterproof or highly-water-resistant stuff sacks or more expensive but drier Cuben Fiber stuff sacks. I like a stuff sack of around 6-9L for my down jacket and 20L or larger one for my down sleeping bag/quilt.
- Waterproof backpack: Even better but a lot more expensive, get a Cuben fiber backpack, with a roll top closure and sealed seams along with stowing your sleeping bag/quilt and down jacket in Cuben Fiber stuff sacks. This is a great way to keep your gear truly dry and is less complicated and time consuming than pack rain-covers or liners.
|Montbell Superior Down Parka – $209|
8.5 oz, 2.5 oz 800+ fill power downAt under 9 ounces this is another great value in an ultralight, fully featured jacket. As Montbell says, “Prized by budget conscious backcountry enthusiasts around the world, the Superior Down Series is “what you need” when a versatile warm layer is critical, minimal weight is paramount, and space in your pack is at a premium.” While not the warmest jacket in the group, it should be more than sufficient for 3-season use.
|Patagonia UL Down Jacket or Hoody – $349 at REI|
This jacket has been a staple of the ultralight crowd for years. My wife and I both own one. It’s not the cheapest jacket but it’s light, and uses a generous 3.5 oz of 800-fill-power traceable down. It comes in Men’s and Women’s, as well as hooded versions for a little more money. The hooded version is hands-down our favorite!
| ||Patagonia Down Sweater Jacket – $230 at REI|
At $100 less than their UL jacket, this is a great warm layer for backpacking or any outdoor activity, really. It’s reasonably light (2.8 oz, non-hooded), and uses 800-fill-power traceable down. It comes in Men’s and Women’s, as well as hooded versions, for a little more money. Of course, there are adorable kids versions as well! Patagonia’s quality, warranty, and customer service are legendary, ensuring you’ll keep this jacket for a long, long time.
|Western Mountaineering Men’s Flash Jacket – $375|
Western Mountaineering has been making some of the finest and lightest down products since forever. And they are legendary for their immaculate construction and their long term durability. This jacket has been a staple of the ultralight crowd for years! Made in the USA.
|Western Mountaineering Men’s Flash XR Jacket – $375|
This is a warmer version (3.5 oz of down) of the Flash Jacket with a highly water-resistant shell. This jacket was my choice for a climbing trip to the Andes in Peru. I summited a couple of 20,000+ foot peaks in this jacket. And yes, that’s a steep price tag but it’s made in the USA.
Lightweight Down Pants and Down Booties
|Feathered Friends Helios Down Pants – $240|
13 oz, 4.4 oz 850+ fill power downThese pants are the real deal. Made with Feathered Friends’ legendary high quality down, these pants offer 4.4 oz of fluffy down, and weigh in at 13 oz. These pants are great for backpacking, but are meant for even more serious high mountain endeavors and offer full-length zips so you can put them on and off over crampons… or, if you’re just too lazy to take off your boots.
|Montbell Superior Down Pants – $169|
8.4 oz, 1.9 oz 800+ fill power downThese are one of the best values in insulated pants on the market. They are warmer and more windproof than fleece pants. As Montbell says, “Prized by budget conscious backcountry enthusiasts around the world, the Superior Down Series is “what you need” when a versatile warm layer is critical, minimal weight is paramount, and space in your pack is at a premium.”
|Western Mountaineering Flash Pants – $250|
6.5 oz, 2.0 oz 850+ fill power downThese are probably the lightest insulated pants on the market. Weighing only 6.5 oz, these are packed with 850-fill down and are built with Western Mountaineering’s standard-setting quality. Don’t get cold, and cranky in camp. Put on your Flash Pants and hang out – enjoy the outdoors, deep into the fourth season.
| ||Feathered Friends Down Booties – $99|
9.3 oz, 4.0 oz 800+ fill power downThese booties are the industry standard. With waterproof removable shells, you can take these with you as camp shoes, then remove the shells keeping the warm down socks on to keep your toes warm all night! These are a toasty-toe delight that will help keep you comfortable deeper into the shoulder seasons and make winter camping much more manageable!
