Five Stars for warmth, comfort, and durability (so far).Three stars for noise.Although before buying, I read many reviews of this leaking after one night, I took the leap and bought one, fully expecting to soon wake up on the ground in in the middle of the night. Still no leaks. Hmmm. Is mine defective?So far it has lasted about 15 nights, including sections of the JMT, Teton Crest, Whitney, Zion NP, and Wonderland. It insulates well, is reasonably comfortable.Although this pad is quieter than some other ultra-light pads, this version still generates adequate volume to startle large predators and wake nearby campers. The farther one hikes each day, the less noticeable the noise.

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'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 as a replacement of my old XTherm (which de-laminated on day four). The new, NXT, pad was leaking from day one of my hike. Of course I tested it at home first, but the leak is so insignificant that takes hours of me laying on it until my hips touch the ground. I'm so tired of the poor quality of Therm-a-rest products that I won't accept this. My previous experience dealing with Therm-a-Rest support have been horrible, with them trying to ridicule me for wanting a replacement. This is my last Therm-a-Rest product. Other than that: It is for sure the warmest pad, when still inflated, but far from the most comfortable. It's a very hard pad because of the type of materials used.
My new NeoAir NXT started leaking on the 3rd day of an independent expedition in Greenland. The leak developed in the corner near the valve, and seemed to have been a manufacturing defect, as there was no visible damage to the outer fabric. I suspect that the way the new valve is attached to the fabric may create stress points around its corners, leading to leaks under pressure.Despite attempting to patch the leak with the included repair kit, the 'glue dot' failed to stick to the fabric (has anyone tried those?). Luckily, my trekking buddy had a third-party kit which worked.Furthermore, the warranty process for international purchases is incredibly inconvenient. If you are purchasing the pad from overseas (Amazon US), then your local distributor (Australia) will ...

If you are purchasing the pad from overseas (Amazon US), then your local distributor (Australia) will not accept a warranty claim. Hopefully, I can return my pad for a refund, but given all the above, I will think twice as to what to get instead.I've been a long-time Thermarest customer and have had excellent experiences with previous generations of the NeoAir. My partner also has a version of the pad with the new valve (although it's not the NXT one), so hopefully my experience is a one-off
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 ... MoreI’m currently completing the Trans-Canada Trail & after less than six weeks my NXT started delaminating itself.

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.
I’ve used thermrest inflatable pads for the last 10 years and I’ve not been disappointed at all. I hiked 3000km of New Zealand’s TA with a neoair Xlite and I slept like a log most nights. I’m a side sleeper and so I deflate the mattress a lot in order to be super comfortable on my side. Whilst the xlite preformed great I would feel some cold on my hips whilst out in colder temps (below 8°C). So the I bought this version (Xtherm) for the enhanced R value rating to deal well with colder temps. I’ve only recently bought this and whilst my aim is to camp out in below zero with it I did camp out in temps of 5°c with this new one and it preformed great. Possibly the cosiest nights sleep I’ve had. Would highly recommend.
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.
