I took this on a

I took this on a 5 day backcountry trip into the Chilcotin mountains. This pad exceeded my expectations in every way. Easy to inflate, simple adjustment for the air pressure to tweak the comfort, and rolls up easily and magically fits back into its own stuff sack. Not all camping gear achieves this last point. . . I regret slightly not getting the rectangular version - the very slight increase in weight would likely be offset by my sliding off the mat less as I am a restless sleeper.

It's super warm, and thus it does its job. It is super loud, and genuinely sounds like a bag of chips. My big issue with it however is that I simply don't find it comfortable, I haven't been able to get a good nights sleep on it.

Comfy and packs down well!

First of all, very comfortable and much improved over my old Prolite Plus. Will say that inflating it with the included bag takes quite a while. Wish the inflater bag thingy was much bigger to cut down on time spent inflating it.

The most important thing is comfort! This thing is comfortable and compact! The extra features, ( bag, repair kit, pump bag) all make this pad a must have for anyone who enjoys the outdoors on any serious level! I like the valve system, I use a flex tail pump and the easy to use wing valve on this pad makes it a breeze to inflate and adjust for comfort. I highly recommend this sleeping pad.

Lightweight, compact, comfortable

Bought this pad for guiding a Denali expedition. It held air just fine and offered enough warmth that I didn't need the Ridgerest I normally put underneath it. It's compact and comfortable to sleep on. It held air all night, every night.

Comfortable enough, and definitely keeps warm. It is crinkly when moving around, at least while new. Maybe it will break in a little and that crinkly noise will go away with some use. It's pretty durable and lightweight. I love how small it packs down! I think with the proper bag and "sleep system" it would be great, however I found it was difficult to stay centered on it as a side sleeper, and my pillow would not stay put. Again, probably more to do with the entire set up rather than the pad itself, but still worth mentioning.

this pad is all round just great super light, warm, durable and comfy. can't ask for more than that from a sleeping pad. was on the fence on buying it because of the price but it is well worth it if you want a pad to do it all.

Warm and lightweight

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 in the night and the mat pressure will increase. 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.

Most durable, however..

I've had the Neoair x-lite w's, and the uberlite. This is the most durable and warm by far, and it's worth the weight if you want to have a inflatable pad that lasts a long time and is warm enough to camp over snow without issues. It would be perfect if it's available in short size: this would cut down the weight and bulk a bit!!

Best pad for all types of camping

I have had the previous three versions of this pad, love every one of them. Usually I buy the big sizes just for extra space to roll, I bought this one regular size for the light weight for an eight month hiking trip, camping across 5 states (3 long trails). I have used previous versions in all temps from sleeping on top of snow to the beaches of Mexico. They have proven to be the best pad I have ever used.

The best got better!

I used my last Xtherm for 9 years. This new model is a solid upgrade. The valve upgrade and increase in thickness are big improvements. Spent my first night in it at -15F warm against the ground. They are the best.

Iditarod Trail-Alaska

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 camping in the desert where everything wants to draw blood. 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.

I haven't fully tested this

I haven't fully tested this pad yet, but so far it has been great. I've just tested it on my hardwood floor. It packs small, easy to inflate, nice and cushy and I can feel the warmth, even in my house. I expect it to be nice, once I get it outdoors in the cold. My only concern is putting a hole in it. I plan to be careful, and always use something under it, never on the bare ground. With the small size, small weight, and crazy-warm R-value of 7, it is just what I was looking for. I can't wait for it to get below zero ;-)

Good Mat

For what it is designed for it's a good mat. I my first trial was on the 18°f concrete sidewalk behind my house and was surprisingly comfy warm for hours. I also slept in a self made snowcave in weather in the teens so the small baffles and mid reflective layer science works. My mat later after a lot of use developed an internal baffle separation and Thermorest acknowledged that and sent me their newer model which was great with much improved inflation check valve and air fill bag design. But the greatness doesn't stop there. I injured my back over a week ago taking a severe blow to all the ribs on my right side of my back falling on the ice after helping an elderly man to his feet. I struggle for days trying to find comfortable sleeping and resting arrangement of the bed and propped pillows and incline for recovery and everything was far to painful until I pulled out the Thermorest Xtherm. It is so comfortable the damage back areas are able have even pressure over all the contours of the body relieving uneven support do to body shape , so the position of the bone connection the cartilage seems to be much happier, I started getting the first real rest without pain using this mat on my bed. Recovery for these is about 4 weeks. Very happy.

By Gregory T.

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.

It far exceeded my expectations in terms of warmth, comfort, small weight, pack size, ans little noise.

With cutting edge Triangular Core Matrix construction and ThermaCapture technology, the XTherm NXT delivers a 7.3 R-value while weighing just 439 g (15.5 oz) 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, therefs no finer sleeping pad than the XTherm NXT.

Therm-A-Rest NeoAir XTherm NXT Sleeping Pad Features

  • Best Warmth-to-Weight Ratio Ever: Refined Triangular Core Matrix
  • Multiple Sizes: 3 size options allow you to get the XTherm NXT that is perfect for your sleep system
  • Premium Comfort: A 3-inch (7.6 cm) thick profile and horizontal baffled structure
  • ThermaCapture technology: deliver a cold-conquering 7.3 R-Value while cutting over 2 oz (57 g) in weight from the previous model
  • Ultralight Durability: 70D nylon on the bottom withstands the wear and tear of extended expedition use
  • WingLock Valve: Delivers fast one-way inflation and rapid deflation without giving up the ability to easily purge air
  • 30D ripstop nylon on top keeps it light and packable
  • Pump sack, stuff sack and field repair kit included
