Best Ultralight Sleeping Pad Reviews
Exped Ultra 6.5R
Best Ultralight
We’re really impressed by the updated Exped Ultra 6.5R, which boasts the highest R-value-to-weight ratio of any all-season ultralight sleeping pad on the market. It is lighter, and quite a bit comfier than competing tier-1 ultralight options like NeoAir, Tensor, and Zoom, while more narrowly besting the heavier Eclipse and Ether Light XR. The comfort and superb shoulder pressure dispersal is all thanks to long, deep channeled baffles across the surface, and its ability to expand sideways for a cradling effect. While it’s plenty warm enough down to freezing, Ultra 6.5R doesn’t sleep quite as warm as its astronomical R-value implies. The double valve system is a bit odd, but the only major drawback is that it uses the thinnest fabric in its peer group; 20d on both sides. For context, NEMO pads use 40d on the bottom, and NeoAir is 30d/30d.
- Price: $200
- Weight: 12.7 oz
- R-Value: 6.9| R-Value/Weight: .54
- Thickness: 3.5″
- Fabric: 20d/20d
- Sizes: Mummy or Rectangle. Both offered in Medium, Wide, Long/Wide
- Pros: Ultralight. Very warm. Highest R-value-to-weight. Great pressure dispersal. Quiet. Perimeter bumpers.
- Cons: Thinner/softer fabric is less durable than others. Independent valves. Doesn’t sleep as warm as R-value implies. Good pump sack.
Sea to Summit Ultralight XR Insulated
Best Value Ultralight
Sea to Summit Ultralight XR Insulated offers an exceptional blend of low weight, high durability, great value, and best-in-class pressure dispersal relative to weight. Compared to many thicker pads, including Ether Light XR, Tensor, NeoAir, Eclipse, Zoom UL, it is comfier on high pressure areas like shoulders and hips. That said, it is both lower R-value (though still warm enough for 90% of summer backpacking) and thinner than the aforementioned models. In regard to its 2.6″ thickness, it is comfier than you might expect to sleep on. That said, users will have to be more intentional about level tent sites, because it won’t block lumps as well. When kneeling on the pad, your knees will power through the resistance and contact the ground directly. As you roll around, your hips or elbow might experience the same thing. While temporary movements are less comfortable, the pressure always reaches equilibrium once you lay down and become static. You won’t experience bottoming out while sleeping, which is what matters most. All in all, a great pad for a great price! See more in our Sea to Summit Ultralight XR review.
- Price: $149 R
- Weight: 14.6 oz
- R-Value: 3.6 | R-Value/Weight: .25
- Thickness: 2.6″
- Fabric: 30d/40d
- Sizes: Regular, Small, Large
- Pros: Ultralight. Excellent pressure dispersal. Durable. Quiet. Great value. Good valve. Size regular is slightly wider than avg.
- Cons: Thinness causes bottoming out, not as good on lumpy ground. Below avg R-value with cold spots.
NEMO Tensor All Season Ultralight Insulated
Top Pick, Ultralight
Choose NEMO Tensor All-Season Insulated because it has one of the very best combinations of weight, R-value, and thickness. The surface dimples form a comfortable and quiet sleeping surface with enhanced durability on the lower half. It’s a smidge heavier than the competing NeoAir XLite, but warmer and better at dispersing pressure for side sleepers. This pad has no major flaws, but those who demand the cushiest, comfiest pads should pass it by.
A lighter and less insulated version, Tensor Trail, as well as a slightly heavier and more insulated version, Tensor Extreme, are also available. Read more in our NEMO Tensor All Season Review.
- Price: $200
- Weight: 14.1 oz
- R-Value: 5.4 | R-Value/Weight: .38
- Thickness: 3.5”
- Fabric: 20d/40d
- Sizes: Regular, Regular Mummy, Regular Wide, Long Wide
- Pros: Incredibly high R-to-weight ratio. Relatively comfy. Thick. Quiet. Stable. Ultralight.
- Cons: Expensive. Comfier pads exist.
Therm-a-Rest NeoAir XLite NXT
Top Ultralight Pick
Therm-a-Rest NeoAir XLite offers the best blend of low weight and high durability in an ultralight sleeping pad, and by far the most classic and best selling option in the genre. It’s an ounce lighter than Tensor, but slightly lower R-value. If you had the old version, you might remember how loud they were, but that is no longer the case; NXT is reasonably quiet. The drawback to this pad is pressure dispersal. Its non-dimpled horizontal baffles simply aren’t that soft to sleep on, and it’s definitely less comfortable and thinner than its primary competitors in NEMO Tensor and Big Agnes Zoom UL. We sometimes refer to it as a surfboard.
A warmer and slightly heavier version, the XTherm NXT is also available. Read more in our NeoAir XLite NXT Review.
- Price: $210
- Weight: 13 oz
- R-Value: 4.5 | R-Value/Weight: .35
- Thickness: 3”
- Fabric: 30d
- Sizes: Regular Short, Regular, Regular Wide, Large
- Pros: Comfy. Thick. Ultralight. Very High R-Value-to-weight. Solid durability and long lasting.
- Cons: Expensive. Flat-ish surface does not disperse body weight pressure as well as others.
Big Agnes Zoom UL
Top Ultralight Pick
Choose Big Agnes Zoom UL because it has the comfiest sleeping surface for an ultralight sleeping pad, comfier than Tensor and NeoAir. Zoom’s generously dimpled surface does a great job of dispersing side sleeper pressure, and it even includes a perimeter bumper to keep you in place. Drawbacks are the fact that it’s slightly less durable than its competitors, and sleeps a bit cooler than the rating implies due to its insulation configuration. It also has a simpler and less user-friendly valve that can be annoying, and is only available in rectangles.
- Price: $200
- Weight: 14.0 oz
- R-Value: 4.3 | R-Value/Weight: .31
- Thickness: 3.25-3.5″ | Fabric: 20D Recycled high-tenacity nylon
- Sizes: Reg, Wide, Wide Long
- Pros: Ultralight. Thick. Comfy dimpled surface disperses pressure. Recycled materials. High R-value. Perimeter bumper.
- Cons: Expensive. Subpar valve. Sleeps colder than rating. Not available in mummy shape.
NEMO Eclipse All Season
Best Value, Tied for Best Light & Comfy
NEMO Eclipse offers an unprecedented blend of high comfort, good insulation, low weight, and reasonable price, making it the obvious best buy in the genre. It offers 4″ of thick, deeply dimpled baffles that do an excellent job of dispersing pressure, even better than Sea to Summit Ether Light XR. Once the pad is weighted, the lengthwise oriented beams create a pleasant cradling effect to keep the user centered. And on top of all that, you get a best-in-class R-Value of 6.2, warmer than any other option in the all-season genre. While we have discerned no major flaws in this pad (it also is quiet and has a good valve), the lack of a mummy cut is annoying, and we don’t want anyone to get too hyped on the thickness. Functionally 4″ won’t be feel much different than 3.5″. Nonetheless, NEMO Eclipse is a lightweight sleeping pad to behold, and we recommend it highly! See more in our NEMO Eclipse Review.
- Price: $160 | Weight: 16.0 oz
- R-Value: 6.2 | R-Value/Weight: .39
- Thickness: 4.0″| Fabric: Unlisted, we estimate 20d/40d Nylon
- Sizes: Regular Rectangle, Wide Rectangle, Long/Wide Rectangle
- Pros: Great price. Very high R-Value. Very thick. Disperses pressure well. Reasonably light. Cradle effect. Quiet, no crinkly sound. Good valve.
- Cons: Light-not-ultralight. Thickness increases have diminishing returns, increase effort to inflate. No mummy available.
Sea to Summit Ether Light XR Insulated ASC
Tied for Best Light & Comfy
For a premium blend of comfort-and-thickness-to-weight, we recommend Sea to Summit Ether Light XR, which is no slouch on warmth or durability either. This is a great all around pad that includes all the best features like a deeply dimpled surface, double valve, perimeter bumpers, and a quiet sleeping experience; much quieter and warmer than its predecessor. And on top of that, the size regular is actually 21.7″ wide, 1.7″ wider than industry standard. Drawbacks come to light when comparing to our top ultralight picks, which are both warmer and lighter, though Ether Light XR bests them in regard to comfort.
- Price: $199 | Weight: 16.6 oz
- R-Value: 4.1 | R-Value/Weight: .25
- Thickness: 3.9” (edge) 3.5″ (middle) | Fabric: 30/40d Nylon
- Sizes: Regular Mummy, Large Mummy, Short Mummy, Regular Rectangle, Large Rectangle
- Pros: Very comfy sleeping surface. Warm. Quiet. Pillow lock feature. Durable fabric. Perimeter bumpers. A bit thicker and wider than average.
- Cons: Light-not-ultralight. Competes with a few even warmer/lighter options.
Zenbivy Ultralight Mattress
Top Pick, Light & Comfy
Choose the Zenbivy UL Mattress because its deeply dimpled surface does the best job of dispersing pressure, and is especially comfy for side sleepers. It’s also quite warm and reasonably light. This is a very comfortable sleeping pad to lay on! However, the depth of the dimples, combined with its modest 3” thickness, leads to an increased likelihood of “bottoming out,” which is noticeable when you put weight onto knees or elbows. We also found the valve to be a bit too tight, so much so that opening it risks damaging the surrounding fabric and glue; durability is a bit of question with this model.
- Price: $189 | Weight: 17.0 oz
- R-Value: 4.8 | R-Value/Weight: .28
- Thickness: 3.0” | Fabric: 20D Recycled Polyester Taffeta
- Sizes: Regular Mummy, Wide Mummy, Long/Wide Mummy
- Pros: Very comfy surface disperses body-weight pressure, great for side sleepers. High R-Value-to-weight. Warm. Recycled material
- Cons: Too easy to bottom out. Modest durability. Not actually ultralight. Pulling overly tight valve could compromise seal.
NEMO Tensor Elite
Best Super Ultralight Sleeping Pad
NEMO Tensor Elite is the lightest and most compact inflatable on the market! Add it to your quiver for fastpacking missions, but definitely not as your daily driver. With 10d face fabric, it’s far less durable than others, and with a summer-only R-value of 2.8. While the baffles are nicely dimpled for pressure dispersal, the surface is quite slippery in a way that negatively affects the overall user experience; it can get quite annoying. This super ultralight sleeping pad has niche applications for FKT setters, but is not a great choice for most people.
- Price: $230 | Weight: 8.5 oz
- R-Value: 2.8 | R-Value/Weight: .28
- Thickness: 3.0” | Fabric: 10d Cordura Nylon
- Sizes: Regular Mummy, Short Mummy
- Pros: Super ultralight. Super compact. Comfy baffles. Quiet.
- Cons: Low durability. Low R-Value. Very slippery. Niche application. Expensive.
NEMO Switchback
Best Foam Ultralight Sleeping Pad
NEMO Switchback is our preferred closed cell foam (CCF) pad, and marginally superior to the more-popular Therm-a-Rest Zlite Sol. Comparatively, it’s a tad warmer and thicker for the same weight. CCF pads like Switchback are great to use while lounging at camp or for a midday nap, because they can safely be used outside of the tent without fear of puncture. However, they lag far behind inflatables in terms of warmth and comfort. We recommend cutting out a torso-ish length section and using it as a supplemental luxury item, or for layering underneath an inflatable to add warmth.
- Price: $55
- Weight: 14.5
- R-Value: 2 | R-Value/Weight: .14
- Thickness: 0.9”
- Material: Closed-cell Foam
- Sizes: Regular, Short.
- Pros: Very affordable. Ultralight. Puncture-proof. Versatile.
Cons: Low R-value. Much less comfy than inflatables.
Gossamer Gear Thinlight
Best Supplemental Foam
The Gossamer Gear Thinlight is a versatile piece of ⅛” thick closed cell foam, far lighter than the aforementioned Switchback or ZLite. However, it is nowhere near cushioned or warm enough to use as a standalone pad. But it is very useful for lounging at camp and/or protecting the underside of your sleeping pad. We recommend the folded version over rolled up. Learn more about it in Gossamer Gear’s 12 uses article.
- Price: $32
- Weight: 3.3 oz
- R-Value: 0.5 | R-Value/Weight: .15
- Thickness: .13”
- Material: Closed-cell Foam
- Sizes: Short (rolled), Regular (folded)
- Pros: Very ultralight. Very versatile.
- Cons: Lowest R-Value. Thinnest. Not a standalone sleeping pad.
Pro Tips & Bonus Info for Buying an Ultralight Sleeping Pad
You might need a higher R-value
The industry standard backpacking sleeping pad temperature rating test (ISO 23537/ EN 13537) is done with a very warm pad — R4.8*. Most pads campers use are not that warm (R 2 to R 3). For instance the popular NeoAir Z Lite closed cell foam is only R2.0. What this means is that as the temperature drops, your pad might prevent you from sleeping warm, even if your sleeping bag is warm enough. Buyer beware.

Tip | Sleeping Pad R-Value Test
The ASTM FF3340 Sleeping Pad R-Value Test is a good thing for consumers. It creates a level playing field where all backpacking sleeping pad manufacturers rate their sleeping pads the same way using a common industry standard test. One manufacturer’s R2.0 means exactly the same thing as another manufacturer’s 2.0.
This standardized test is relatively inexpensive and easy to do allowing all sleeping pad manufacturers access to the test. This is what allowed us to do real comparisons between sleeping pad performance for R/weight and R/cost. As of this writing most pad manufacturers have tested their pads for R values. Woot!
How does the 2020 advent of ASTM F3340 Testing Impact Temperature Ratings?
The backpacking sleeping pads themselves did not get warmer or colder, they are the same as they were! It’s just that the new ASTM FF3340 Sleeping Pad R-Value Test is run slightly differently than Therm-a-Rest’s old test. See examples below:
NeoAir XLite Example | Air Inflated Pads
The old test value was based on 80% of fully advertised inflated thickness of 2.5” — Therm-a-Rest was being conservative. But in reality the backpacking sleeping pad fully inflated was 2.75”. The math works fairly linear here. Old Test 2.5” x 80% = 2.0 inches and New Test 2.75” fully inflated is about 35% higher. That’s very close to the 31% increase in R Value from R3.2 to R4.2. And the average increase in R value for T-Rest Air Inflated pads is 30%.
ZLite Sol Example | Foam Pads
Compared to the old test, the new test puts more weight on a smaller area on foam pads. And foam pads are less able to distribute that pressure. More pressure in a smaller area translates to more sleeping pad thinning than the old test. A thinner sleeping pad has less thermal resistance, or lower R value. This accounts for the approx. 25% decrease in R value for foam pads than how they were previously measured. But again, in the field, these pad sleep just as warm as they ever were!
We used the R5.4 Therm-a-Rest NeoAir XLite Sleeping Pad “Women’s” to camp on the Southern Patagonian Ice Shelf.
Which Backpacking Sleeping Pad is Right for Which Season?
Use Expected Temperature to Choose a Sleeping Pad for backpacking
First, we think expected temperature is a better way to choose a sleeping pad for backpacking as opposed to “seasons” which is the way that the industry traditionally talks about which backpacking sleeping pad is right for which conditions. For instance winter in Florida is very different than Winter in Maine.
Second, we are more conservative and generally choose a sleeping pad for backpacking that is warmer than is usually recommended. Remember, the standard sleeping bag temperature rating test is done with a very warm sleeping pad — R4.8.
Which R-Value for which temperature?
R2 to R3.5 | Nighttime temps well above freezing: When nighttime temperatures are above freezing (with possibly a light morning frost) average to hardy sleepers will want a backpacking sleeping pad around R2 to R2.5. Colder sleepers will likely want an R3 to R3.5 pad.
R3.5 to R5.4 | Good portion of nighttime temps at or around freezing: When a good portion of nighttime temperatures are at or below freezing (with possibly a very hard morning frost) average to hardy sleepers will want a sleeping pad for backpacking rated from R-3.5 to R-4.5. Colder sleepers will likely want an R4.5 to R5.4 sleeping pad.
For most folks in the northern part of the country or in the high mountains Therm-a-Rest NeoAir XLite NXT is the best overall pad for the shoulder seasons of late fall or early spring, when snow and temps falling well below freezing are a real possibility.
R5.4 to R7 | All of night time temps at or well below freezing: When temperatures are already below freezing before you go to bed (with possibly of morning temps dropping below 20F) average to hardy sleepers will want a backpacking sleeping pad around R5.4. Colder sleepers will likely want an R6.5 to R7 pad.
Both campers might consider adding foam torso kicker-pad to increase warmth in the critical upper body area, or a supplemental mat like the Gossamer Gear Thinlight. The applies when camping on snow or ice. When a high R-value backpacking sleeping pad is called for, we always turn to the Therm-a-Rest NeoAir XTherm NXT.
Tip | How to Prevent Punctures
The current breed of air inflated pads are useless if they leak, although they can be field repaired. As such, you need to take care to not to puncture, abrade or otherwise abuse them. Make sure you clean your campsite (and tent floor) of all pointy and sharp objects, rocks, pinecones, sharp sticks, thorns, cactus spines etc. If not in a tent, a good ground cloth between your sleeping pad and the bare ground is always good.
And finally, we do not recommend you tightly fold and roll-up your pad in the supplied stuff sack. This creates undue folding stresses to the fabric that in time can result in distributed micro punctures that manifest in slow leaks. If your backpacking sleeping pad is deflating over 2-6 hours, this is likely the cause. Instead, loosely roll your pad up without folding it — no need to get it super tight. Then make a gentile bend in it so you can fit it in your pack. Again, make sure it is not rubbing against sharp things in your pack. [see picture]
Tip | How to Field Repair Ultralight Sleeping Pad Punctures
We’ve had good results with field repairing backpacking sleeping pads and find that the NeoAir series in particular takes well to repairing. Clean the damaged area with alcohol and apply the manufacturer’s supplied repair kit patch, or Tenacious Tape. This can work on small to medium sized punctures. To find a puncture, you can put your pad in a stream or lake and look for bubbles.
Barring that, pouring water over your pad and spreading it out with your hand will also work. You can even put your ear to the pad to listen for a puncture. Once located, use a pen to draw a circle around the hole and thoroughly clean and dry the area — a bit of sunlight does wonders for drying. If you have an alcohol stove fuel or an alcohol wipe in your first aid kit, you can use them to get the area really clean and improve patch adhesion.
