I have been positively surprised by this products insulation properties. Thought the theory presented about the internal airflow with the cold air being kept to the ground and the air heated up being circulated at the upper part of the sleeping pad would be mostly marketing, but it appears that it actually works. Used it for a weeks trip in tent so far and has been used in combination with a ridge rest sleeping pad without any signs of the cold coming through. Similar in warmth to the downfilled Exped product, but have been very disappointed with the Exped product where I had to sleeping pads exploding the same day at 4500 m elevation in Nepal without any mechanical impact.

Talking to the guide at the same trip, he mentioned that the same thing had happened to 15 out of 16 Exped down filled sleeping pads that he had bought, so would discourage anyone from purchasing that product if a robust sleeping pad is needed. Have had Therm-a-rest products for many years and the only weakness detected so far is that the glue is a little heat sensitive, so destroyed a couple of matresses when sleeping on a floor heated by an open fire in a traditional housing in Korea.

Comfortable and war, but pump sack could use

Comfortable and very warm (though we only used the pads in California's Mediterranean climate in late December this time, I expect that they will do well in snow). WingLock valve is easy to use. Inflation via pump sack could be ibetter, as it takes longer to fill the pad, compared to the Nemo Tensor that we also own. While it takes 3-4 single puffs (meaning one puff to fill the sack each time) for Nemo Tensor, it took several repeats (with two breaths for each fill - totaling 15-16 puffs) for NeoAir. Not sure this is due to thinner pump sack than Nemo's or not. Nemo Tensor's pump sack also has a firm soft rubber at the opening, which is easy to hold the sack and makes the sack less collapsible between each breath (a single good puff fills up the Nemo sack). ... MoreComfortable and very warm (though we only used the pads in California's Mediterranean climate in late December this time, I expect that they will do well in snow).

Unfortunately, we now have three NeoAir Xtherm MAX (purchased this time) and one Nemo Tensor, and the total time to inflate all four pads is long. To be fair, attaching and removing pump sack is a lot easier with NeoAir Xtherm than Nemo Tensor.

Comfortable and warm sleeping pad

I’ve spent years sleeping on a cheap sleeping pad and finally upgraded to the Therm-a-Rest NeoAir XTherm NXT Sleeping Pad. Truly a game changer. Not only was side sleeping comfortable, but I was also shockingly warm. I’ve only tried it out in low 30’s temps (with high winds) but was super toasty in a 18 degree bag and just a wool base layer. The ground was very cold and I was amazed that I wasn’t able to feel it through the pad. The one down side is it’s very narrow - don’t expect to have any spare room on the sides. As a straight-sized woman (size 6) I felt like I barely fit on this pad. I know they offer a wide size, but overall it doesn’t seem very size inclusive. I also noticed my sleeping bag was very slippery on the pad, not a dealbreaker but I had to be ... MoreI’ve spent years sleeping on a cheap sleeping pad and finally upgraded to the Therm-a-Rest NeoAir XTherm NXT Sleeping Pad.

Compact and Comfortable

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. ... MoreI 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 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 have very mixed feelings

I have very mixed feelings about this product. I've used it 6 nights now so here's my opinion:Bad: It is definitely loud. It sounds like you're opening a potato chip bag every time you move. It's also quite thin for us side sleepers to where my hip will hit the ground even if it's fully inflated. The bag to inflate is hard to get on and off, and makes me concerned that i am going to break the valve. It doesn't pack down as small as i was expecting.Good: It is very warm. Great for cold nights and anyone who tends to run cold in general. I thought i needed a warmer sleeping bag for the fall & winter but now my bag is just fine.Other notes: The first item i was sent ended up being the wrong size. The order and the box were correct, but the actual pad inside the box ... MoreI have very mixed feelings about this product. I've used it 6 nights now so here's my opinion:Bad: It is definitely loud.

The order and the box were correct, but the actual pad inside the box wasn't what it was supposed to be. Not sure how this happened, but it was a hassle to reach someone for a return since there was no number to call and get them to send me a prepaid shipping label. I didn't feel I should have to pay for the shipping fees since it was their mistake. The whole exchange process took about 2 weeks and I missed using it on a backpacking trip that i was looking forward to having it for.

Lightweight and reliable sleeping pad

This Therm-a-Rest NeoAir XTherm NXT Sleeping Pad is super lightweight and reliable. It provides decent comfort for a blowup sleeping pad and provides warmth from cool ground. It comes in a soft blue-green color, which I like, though I suspect it'll start to show some dirt after using it a while. The material is kinda crinkly, and thin, but seems pretty durable.The sleeping pad came with a repair/patch kit, an air bag for inflation, and a carrying bag. The air bag for inflation only kinda works and you still have to blow air into it in order for it to inflate the bag. Luckily, the pad can be inflated the old fashioned way or by self inflation. It has a one-way valve that made inflating it manually pretty easy and it didn't take much air input to get it inflated. ... MoreThis Therm-a-Rest NeoAir XTherm NXT Sleeping Pad is super lightweight and reliable.

The pad holds air very well once it is inflated.The regular size is very long for a regular! Which, for me, is great. I am 5'10" and still have some room on the ends. However, it is fairly narrow and only provides a tiny amount of space for turning over.I was only able to use this for one tent camping trip so far, but, overall, I think this is a good product and I am excited to add it to my camping and backpacking rotation!

Obviously warm if a bit noisy

Writing this review less than 30 minutes after this pad was delivered, so obviously I haven't field-tested it yet and can't speak to longevity. That said, I'll start from the setup: inflation is a breeze IF YOU KNOW HOW TO USE THE PUMPSACK -- hold the sack open and blow into it from ~12 inches away, this will instantly open the sack fully at which point I just ham-fistedly clamp the end of the sack shut and then smash it. Took 5-7 "pumps" to fill the thing, probably 30-60 seconds, no time at all. Opening the "valve" on the pumpsack and snapping it onto the valve of the pad both took more force than expected, and frankly I don't understand why there's a lid/cap on the pump sack to begin with, like why would I want the bag's only purpose to be inaccessible at any ... MoreWriting this review less than 30 minutes after this pad was delivered, so obviously I haven't field-tested it yet and can't speak to longevity.

It makes a lot of crinkly noises as I move around, maybe like crinkling a plastic grocery bag under a medium-weight blanket, so a bit noisy but not any louder than other lightweight backpacking gear so I'm not complaining about it. My shoulders are roughly 16" across so those fit fine, but I will be relying on my sleeping bag to stop my hands from falling off the sides of this pad. If this product weren't discontinued I'd commit to updating this review later, but by the time I can do that there will be no point. Hope this helps anyone catching the last sale price!

So far so good

Slightly cold to the touch initially which was something new to me (coming from klymit insulated v where the fabric somehow just doesn’t feel cold to an initial touch even at -12c but was starting to not be insulated enough). Think touching a metal spoon versus a plastic one, thermal conductivity must be pretty high on the Therm-a-Rest outer fabric. At extreme cold I could see this being a problem if you need to shift around, as any expenditures of heat to warm up the material is going to be rough. That being said, 70D on the bottom definitely feels durable but I’d only personally set it in a tent or groundsheetI have the regular and find my arms slightly hang off the sides if I’m on my back, haven’t noticed this to be annoying yet but might go for the wide if so. ... MoreSlightly cold to the touch initially which was something new to me (coming from klymit insulated v where the fabric somehow just doesn’t feel cold to an initial touch even at -12c but was starting to not be insulated enough).

I’m 5’7” and maybe 130lbs. This packs down so well and is roughly an ounce more than what the package claims but insanely light for the comfort and insulation.I’ve only had it one month but have taken it down seven nights to low 20s deg without any problem using a Katabatic 22deg flex quilt and only underwear. Plan to take it to -10 in about two weeks and will update the review then.I find I fold in thirds lengthwise then roll the mat fairly easily into the provided stack (my klymit was painful to get all the air out of) often taking care to make sure the wing lock can just gently fit between the roll so it isn’t strained weird. Time will tell if this holds up, but I’m personally skeptical of the winglock and it’s durablity unless you pack it with care.I enjoy using the pump sack but prefer my quilt in it’s provided sack so I’m trying to find a use for the pump sack so it isn’t just deadweight.As a heads up to future buyers, Therm-a-Rest is coming out with a new mattress that is supposedly warmer and lighter. I’d like to use this for every season to save money so we shall see if I can tolerate the r-value during humid/hot nights, I sleep pretty hot so I might be unlucky but will update my review accordingly

This pad is a great choice for cold weather Backpacking-Mountaineering and possibly the best

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 ... MoreThis 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.

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.

so worth it, best sleep while rough camping ever!

I never thought I needed an inflatable sleeping pad, but this makes such a world of difference, I'm so glad I have it now! I've been on three camping trips since purchasing the Therm-a-Rest NeoAir Xtherm MAX Sleeping Pad. All of them were under cold, wet, muddy/sandy conditions, with long hard days that strain your muscles to the breaking point. I was so surprised to find that the sleeping pad not only kept me super warm (the ground froze overnight), but it was so comfortable that my muscles actually relaxed and recovered overnight!I'm 5'2", so this pad is luxuriously large for me, with extra room for my dog to snuggle on a corner while I sleep. I normally sleep on my side, but had to switch a lot from side to side and over to my back to ease the pain from a back ... MoreI never thought I needed an inflatable sleeping pad, but this makes such a world of difference, I'm so glad I have it now!

I normally sleep on my side, but had to switch a lot from side to side and over to my back to ease the pain from a back injury. The pad stayed put, was comfortable in all positions, and I woke up more rested than I've ever been in my tent.The pad also held its air really well. On one trip, I kept the same base camp for four days, and the temperature swung from below freezing at night to mid-60s during the day, but after filling the pad on day one I never needed to top it off.
