With cutting edge Triangular Core Matrix construction and ThermaCapture technology, the XTherm NXT delivers a 7.3 R-value while weighing just 15.5 oz (439 g) in the Regular size. Put another way, the best warmth-to-weight ratio of any sleeping pad ever created. It is warmer, lighter and thicker than the previous model, which is why the XTherm NXT cements the legacy of being the go-to sleeping pad for alpinists, mountaineers and extreme cold expeditions. At 3-inches thick, with horizontal baffles, all-night comfort and support are at hand, while 70D nylon on the bottom ensures the XTherm NXT holds up to extended expedition use. The WingLock Valve allows for rapid inflation and deflation but is also intuitive and easy to use in frigid weather when the gloves are not coming off. If reliable overnight warmth is the demand no matter how far the mercury dips and space in the pack is at a premium, there’s no finer sleeping pad than the XTherm NXT.

I received this Therm-a-Rest NeoAir XTherm NXT Sleeping Pad Regular Wide for free from the REI Trailblazers sampling program in exchange for my honest review. I'm a car camper that goes to developed camp sites or hot springs, and don't really care about weight or space, but this is compact and light. It took me about 7 minutes to inflate using the air sack. Using an older Thermarest Neoair battery inflator took 25 minutes, was only partial inflation, and it was a struggle to fit on the newer valve, because it is made for the older valves. I never blow into the bag or the pad because I don't want moisture in the chamber and the possibility of mold growth. Deflation is very fast opening the main valve and the wing adjuster. I like that there is a repair kit included. ...

I like that there is a repair kit included. The packaging is minimal, no inner plastic bag or desiccant. The box has a cut out so you can feel the material. There was no chemical smell or off-gassing for me. I initially over inflated because I was worried temperature drop would decrease inflation, but going from mid 70'sF at dusk to 48F didn't effect inflation. Perhaps more of a factor in much colder weather. I deflated the pad a bit in the middle of the night using the wing adjuster while I was cozy in my sleeping bag on the pad, making it was more comfortable, and I slept well. I sleep on my back, side, and stomach. I had a 40F sleeping bag with a cotton liner and it was great temperature wise at 48F. I've had a Thermarest Mondoking XL which is both foam and air, that is my go to, but it's enormous, heavier, and takes a longer time to inflate/deflate and a struggle to pack away. The Mondoking is more comfortable because it's foam and air and larger, but the NeoAir XTherm NXT is pretty comfortable for only air, and the wing adjuster makes it easier to achieve your particular firmness level while on the pad. I think this product is great if you want a 4 season sleeping pad, want to save space and weight, and appreciate quicker inflation and packing time.

I normally used just a foam pad and it worked ok but wanted to try this lighter and more compact Therm-a-Rest. It took me maybe 10 min struggling with the air bag to inflate, until I noticed that the valve wasn’t fully in the right position. My bad. Yet I made a mental note to get a mini pump, would make it easier. Slippery: the pad is reversible, as far as I can tell. Not sure why that is needed. I would prefer a one that has a stronger and non-slippery bottom. My tent was pitched on a slightly inclined terrain and it slid down by the morning. Size: I got a regular-wide version, I can tell it was barely wide enough for me, an M/L-size male. Warmth: my perception after the first night was that it is really warm, the insulation part worked great. Noise: my complaint ...

Noise: my complaint would be the squeaking and scratching sounds the pad makes on your every move. It is something expected from an inflatable (although I think for the premium pricing I’d expect the company to make an effort to minimize that) but between the nature and human noises from outside, and me rolling trying to accommodate myself better and this thing responding to any movement I did not have a good sleep. Overall, I think it is a good pad many people would find great, but it takes time getting used to and I’m not sure it is worth the effort. A quality sleep is really important when you face a hard climb next day.

This review is regarding the non-NXT version, but, I am very skeptical to there being any difference. I bought three products about a year ago, and all three of them had serious manufacturing issues. The XTherm de-laminated after a weeks use, and this because of obvious manufacturing issues. It looks like they had dropped one of those stripes on reflective film on the diagonal, inhibiting lamination in that area, which lead to de-lamination starting from that point. Since it's been over a year since I bought it, and the new NXT version is out, their Swedish representatives said that I won't get a replacement.

The other products are the pump-sack which de-laminated within a few uses, and the the Parsec 20F that came loose stitches. They are all products with some of the best designs out there, but the quality of manufacturing is very poor.

My mattress is a few years old and has seen about 20 bag nights. For 15 of those, it served me well. I don't care about the crinkly noise – it's a necessary evil to have both light weight and warmth. Then the valve randomly seized and I had to replace it. I checked and rechecked the new valve for leakage with soapy water, then immersed the whole mattress in a full tub of water while it was inflated, holding one section at a time under the water as my girlfriend looked for bubbles. Nothing. After all that, I just spent 5 nights in the Enchantments on a mattress that had to be reinflated twice each night. Needless to say, my sleep suffered.Thermarest pads of old lasted forever. I still have my originals and loan them to friends. That's great value when considering ... MoreMy mattress is a few years old and has seen about 20 bag nights. For 15 of those, it served me well.

I've used these pads on the Appalachian Trail, Iditarod Trail, Arizona trail and more. The new valve is a big upgrade as it allows you to inflate the airpad faster. I selected the Regular/Wide X-Therm for an independent solo trek on Alaska's Iditarod Trail in February '23. I mostly cowboy camped or used an UL Tarp to protect me from precipitation. This airpad worked well to insulate me from the snow. I used a -40F sleeping bag and I was tolerably comfortable in temperatures down to -30F and I didn't die when the temps dropped even lower in the final stretches of my 350 mile trek. When I head to the arctic next year, I'll add a foam pad to increase the insulating properties when sleeping on snow.It is important to protect these pads from puncture, particularly when ...

The only other drawback I have found, is that the provided bag for inflating the pad, is useless in extreme cold. The plastic becomes extremely rigid and will not attach to the pad's nozzle.I highly recommend these sleeping pads.
Got this product from REI after extensive research. First multi day camping trip was ruined as this new pad kept deflating on me. Thankfully it wasn’t very cold or I’d have been in trouble. Second trip same thing happened, but I learned my lesson and brought my backup Big Agnes pad. I have since checked it. Valve is good. No holes to be found. But doesn’t hold air. Must be at the seams. On that note BA warranty is great compared to thermarest. Therm-a-Rest wanted me to waste my time searching for the leak first after selling a nearly $300 pad. Then they told me to mail it back on MY dime and there will be a 6 week turn around and if they deam it to be manufactured defect they’ll replace it. BA warranty experience was incredible.

They apologized, asked for proof of me destroying the old pad. And they mailed me a brand new, newer version of my old BA in a timely fashion. I’m hoping that after I get this back from Thermarest I can actually enjoy it like all the glowing reviewers have. Not sure I’ll ever quite trust it though.
I’m currently completing the Trans-Canada Trail & after less than six weeks my NXT started delaminating itself. I obviously would expect some wear & tear through continuous use over time but not this quickly especially as I know a lot of thru-hikers rely on Thermarest. I also hadn’t been using it every single night over this time.I became hopeful when I saw that Thermarest almost always replace this under warranty as it is a manufacturing defect so I applied for replacement over two weeks ago now & still have not heard a thing. I understand that they go through requests in order received but it’s really discouraging to know that they are getting this many requests that it’s taking that long to get to mine.

Like is the quality of their products so bad that that many people need to be applying for warranty? It’s just extra frustrating as I have not had a good sleep on trail since this has happened as I’ve been trying to still use it as best I can while I wait to hear for next steps. I have finally ordered a replacement bed mat now (not from Thermarest obviously) but I don’t think this is very eco-friendly needing to double up & it also kinda defeats the purpose of trying to be ultralight by having a back up bed, right?? Just so many frustrations overall - like I get that defects happen & it sucks but ultimately just frustrated at how slow their customer service is when my bed is my lifeline right now.
This pad is a great choice for cold weather Backpacking-Mountaineering and possibly the best, considering that it holds the best weight to insulation ratio and also being very durable due to the 70d fabric at the bottom side. Considering the above, some minor drawbacks (bellow) can be excused. I have had the pad in all its versions, with the Classic valve, the Winglock valve and now the Nxt. Have spent many nights on the mountain on it and has never failed or had a puncture ( I always sleep in a tent with a groundsheet ).Comparing it with the previous version with the Winglock valve, the comfort is better, the weight has marginally increased (+20g), the insulation has marginally increased; the upper fabric provides less grip.Specifically:-More Slippery to the ...

Preferred the duller two tone grey of the previous version but that is a personal preference.-The problem with the pump sack remains. It is not seam sealed, therefore after some use, it starts to lose more air from the seams than it does when new. This results in an increase in the the time it takes to inflate the pad: 6-7 full pump sacks when new, 10+ after some use. You can always seam seal the the seams yourself and this will improve the effectiveness of the pump sack significantly. However because of the construction of the seams a full seam seal is not possible, it will always lose air when being pushed.-The specific pad ( size R) that I received weighs 462g not 440g as stated. Another one a friend got, weighs 458g. The previous version with the Winglock valve that owned weighted 440g. (Size R).-The increase in thickness ( now at 7.6cm ) is welcome. Now you can seat on it and you will not touch the ground for an instant as with the previous version at 6.4cm thickness. When laying on the mat you can also increase the comfort of the pad since the extra thickness allows to use it with less air.-The increase in R-value is also welcome. However the previous insulation value at 6.9 has been more than adequate even when sleeping on snow.-The noise of the pad did not bother me at all, there is slight improvement in the new version. I think that this whole matter with the pad being noisy is overrated.
I bought XTherm NXT because my current mat had a low R-value and was not warm enough on cold nights. The new Thermarest XTherm NXT performed well on a recent 3 day hike into the Kosciuszko National Park in Australia. All three nights were below zero temps, the coldest being around -7C. Combined with a good sleeping bag, I was warm and comfortable. The NXT packs down to a reasonable size and the stuff sack is big enough that you don't need to be overly careful how you roll the mat to get it back into the bag, including the pump sack. The pump sack was a great addition and, while it take longer to inflate, it's far more relaxing than blowing a mat up.I'd advise keeping the mat slightly under inflated when you go to bed because your body temp will raise the pressure ...

It's not hard to release a bit of air if you need to but better to avoid the problem in the first place. The XTherm NXT is a good thickness and keeps you off the ground even if you like a slightly softer inflation like I do. the mat is a bit noisy when you roll over but it is not noisy for small movements.I am 183cm tall and bought the large version. Combined with the extra width of the large, I did not have to worry about rolling around in the night and staying on the mat. The extra room was worth extra weight in my opinion. If you're less than 183cm, consider the regular or regular wide version.
I bought this for backpacking long distances like the Colorado Trail. I am lightweight backpacker, but I also sleep cold, and those two traits tend to not go together. I tend to get too cold at night, and that makes it hard to find lightweight gear while also staying warm . I’ve been waiting for Thermarest to make a warmer pad that’s also lightweight and this is the one. Certainly not as comfortable as my foam mattress at home that I sleep on daily, but it is comfortable and keeps me warm for backcountry sleeping. It’s also so lightweight!The downside is it does take a while to blow up with your mouth, which can be hard after a long day of 20+ miles on the trail. But I’ll take that savings for the weight .

They’ve greatly improved on the crinkly sound that older models make (and honestly made me return previous models). As a side sleeper, I found myself slipping off the side a bit, but you could just tuck yourself closer to the tent wall or put an object there to prevent.I am 5”5 and 125 pounds and it fits me perfectly
