Made for winter camping without adding unwanted weight or bulk to your pack.

You're headed out for a week of backcountry touring. And, since you're no longer allowed to sleep on any of the beds in the yurt, thanks to your little incident last time with a cigar and some kerosene, take the Therm-a-Rest NeoAir XTherm Sleeping Pad. This toasty pad gives you insulation power and a bit of cushioning from the hard floor.

  • Lightweight, insulation-free design has an R-value of 5.7, which means this pad has more comfy, warm insulating power than those ultralight-feels-like-cardboard pads
  • Nylon soft grip with textured top and bottom keep you from slipping off the pad in the middle of the night while remaining durable for long, rugged expeditions
  • Tapered shape fits your mummy bag while reducing weight and bulk
  • Patent-pending Triangular Core Matrix uses more than a hundred cells to keep air from shifting around for a more stable sleeping surface compared to other non-insulated sleeping pads
  • Inside its 2.5-inches of cushioning are two layers of cells and patent-pending Reflective Barriers, which allow the top cells to recirculate your heat and the bottom layer to insulate against the cold Earth
  • NeoAir insulation-free technology lets you pack the pad down to a 9 x 4in roll (regular) for easy storage in a pack while weighing less than a pound
  • Inflation valve can be inflated by mouth or by using the included pump valve and sack
  • Pump valve can be fixed to any plastic bag or compression sack for inflating without having to catch your breath in high elevations
  • Included repair kit permits quick fixes during your long treks
  • Four sizes, small, medium, regular, and large, fit your size and weight preferences
  • Made in Seattle, WA to keep things domestic

great durable pad

  • Familiarity: I've put it through the wringer

Love this thing, its long enough for a tall guy like me at 6'5" and durable to last multiple outings in the winter and I use it in the summer. Keeps the cold away and it very comfy.

I've been trying to decide between this mat and the NeoAir all season. Does anyone have any comments to help me decide.
There is a small R-value difference (4,9 compared to 5,7) would i find any difference?
To me it seems like the all season is a little bit more durable, does anybody know if that matters at all, i mean would there ever be a time where one would leak because of that but not the other?
And there is a little weight difference, 140gr. Doesn't seem that much seeing that there is more room on the all season. I had the thermolite plus and I sometimes woken up when my feet slip outside onto the snow.

if anybody could help that would be great!

I have the X-therm. I haven't beaten it to death, but I don't have any real worries about its durability. It's a clearly well-made piece.

The large X-Therm is quite large, and I have no issue staying on it. I will say that because it's tapered, it fits a little better in some tents, and the rounded shape at the top makes it easy for me to have stashes of things around my head but clearly off the mat.

So... X-Therm is a little warmer (20%), a little lighter, and probably fits a little better inside a tent. Pricier though. My guess is that it packs way smaller too (mine rolls up into a nalgene sized roll--even when I'm packing quickly in the woods).

Very happy with the X-Therm.

Warm and mostly comfortable

  • Gender: Male
  • Familiarity: I've put it through the wringer

I bought this about a year ago. First one I had was defective- there was a pinhole leak I discovered 4 hours into the night on a 4 day hiking trip. I RMA'd it for another of the same type and that one was fine. Always sleep on your inflatable pads the night before you leave for a trip!

Anyway, I got the regular size pad and use it as my only pad, year-round. I have a bad back and have had back surgery- spinal fusion among other things. This is basically the only way I can sleep outdoors. As such, I probably have more exacting standards for comfort than most.

The pad is fantastically thick and once you let some air out, it's very comfortable. It's also warm. I took it into Shenandoah for several days in January and it hit 7F. I've never slept so soundly and so comfortably. It was fantastic. The noise isn't nearly as bad as everyone says unless you're doing cartwheels on your pad. It is there, though, so be wary of that if you're hiking with people that demand complete and utter silence while sleeping.

It's not all great, however. The pad is ~18" wide when inflated, not 20. I'm a wide guy and if I'm not in a very snug sleeping bag, my hands and arms will go right onto the ground. Not great when freezing. Thermarest needs to make a regular/wide pad and/or medium/wide, not just a long/wide one.

Edit: It also folds up and stuffs easier than any other inflatable pad I've ever used. The included sack for blowing the pad up is completely useless. You'll be using your mouth.

Totally agree with your comments on the width. Thermarest/Cascade Designs really needs to offer a Regular Wide pad that's 72" long and 25" wide.

Warm pad, but noisy for a fiddly sleeper like myself.

  • Familiarity: I've used it once or twice and have initial impressions

This is one WARM pad! I just used this for a winter snowshoeing/camping/ice fishing trip in the BWCA in February. Overnight temps were between 0 and -25F. I slept in a Feathered Friends Ibis Ex 0 bag and the XTherm performed great! I could feel the heat radiating back at me from the pad. For comparison, I tried out my Exped SynMat UL 7 on a 0 degree night and was very noticeably colder. The XTherm wasn't nearly as noisy as I expected and has nowhere near the crinkle of the regular NeoAir. The stuff sack/pump is a little cumbersome. It's not nearly as simple to use as the Schnozzel but it gets the job done. If you're looking for a warm, lightweight, warm, packable and warm pad, look no further! Did I mention it's warm?

Never again...

  • Familiarity: I've put it through the wringer

... will I go winter camping without my Therm-a-Rest NeoAir XTherm!!
Being female, I get cold more easily than the average burly mountain guide. This lightweight, packable, comfy-as-sleeping-on-the-ground-gets sleeping pad in combination with a zLite Sol kept me warm in Antarctica with temps well into the -20F range. Bravo!

Is this pad going to be too hot for camping...

Is this pad going to be too hot for camping in the summer? I'm trying to find the happy medium between keeping me warm enough in the spring/fall (I'm a cold sleeper) without overheating me in the summer.

Responded on

The Therm-a-Rest NeoAir X Therm Sleeping Pad is actually Therm-a-Rest's warmest pad at 5.7 R value and it is intended primarily for winter use. That being said, they also consider it a 4-season piece of equipment. This will keep you warmer even when you don't necessarily want to be but that is the price you pay and its versatility is limited somewhat by how well it functions in the winter. If I had the money I would get another lighter pad to go along side this, but that depends on if you really want to buy pads for different times of the year.

Best Answer Responded on

I love using it in summer because it allows me to use a sleeping bag with a lower temperature rating. It is the one mattress to rule them all.

Responded on

The R value tells you its insulating ability. A higher R means you're better insulated. The ability to transfer heat between the body and ground is less in a high R pad. A high R pad won't warm you up by generating heat but it will help you maintain your body temperature better. In the summer when your body is hot, a high R pad won't transmit the heat to the ground.

I just got my xtherm a couple weeks ago and brought it straight out for use. I took it on a 3 day trip thought the black mountains of North Carolina with the first night getting down to 10F and the ground was covered in a couple inches of snow. This pad was not only extremely comfortable but it was also incredibly warm, the moment I laid on it I could feel my on body heat radiating back at me. The only thing I was really worried about with this pad was whether the pad would be to loud since I've read a bunch of reviews of how it's like "sleeping of a bag of potato chips" but that could not be further from the truth you can hardly hear a crinkle or anything at all for that matter.

Essentially perfect

  • Familiarity: I've put it through the wringer

I bought this tent as a replacement to my old thermarest (self-inflating foam core). It is MUCH lighter, packs smaller, is actually more comfortable than my old pad of similar thickness. It is super warm in cold weather, but doesn't feel hot in warm weather. The ONLY possible trade-off is the fabric feels less durable than my old school thermarest. As such I am reluctant to put in my chair frame for fear of puncturing this expensive pad. I still carry my chair frame with me, but use it without the pad in it - which is actually much more comfortable than it sounds. All in all a fantastic piece of gear!

Warm for it's weight

  • Familiarity: I've used it several times

This is the warmest sleeping pad for its weight that I have found. The fabric sounds a bit like wrinkly plastic, but you must live a very luxurious life to let that bother you.
It's very easy and fast to inflate, unlike some of those down-filled mattresses.

Shakedown results: Not for side sleepers

  • Gender: Male
  • Familiarity: I've used it several times

Used the Xtherm on a recent AT trip and found it lived up to it's rep for warmth. Amazing pad.

-- When laying flat on the pad, it almost feels as if there is an active heating process happening--as your body warms the upper air chambers in the pad, you can FEEL the pad warming up and reflecting back at you. It's cozy.

-- Not great for side sleepers. Because the warmth of the pad relies on body heat being reflected around/back at you, side sleepers don't "give enough" heat to the pad to feel its warm embrace in return... there's just not enough input to get any output. If I was a side sleeper (I've dabbled, but heck, everyone experiments in college...) I think I'd look for a pad with more traditional insulation.

For me, it works. Super warm, great convenience features, super comfortable.

First Impressions: Impressive Design

  • Gender: Male
  • Familiarity: I've used it once or twice and have initial impressions

Just unboxed it... but plan to bring it to the AT next weekend. Some details that come from the unboxing:

-- Took a little over three minutes to inflate. I was focused on the work, but not letting myself get lightheaded.

-- The stuff size is impressively small and the whole unit is surprisingly light. (Stuffs to about the same size as a Nalgene 32oz bottle.) This is for the large size.

-- The stuff sack functions as a pump and includes a pocket for the included repair kit.

-- Once inflated, it is surprisingly comfortable, and if you desire to lighten the pressure, easy to reach over your shoulder to adjust the valve.

-- The large is long for me (5' 11") but only just. The width is just about perfect--my shoulders are supported but the pad is not really any wider than I am.

-- It IS noisy, but not as bad as I thought it would be. I would say it's as if you are sleeping on top of a couple flattened paper grocery bags. There's a crunch, but it's a low pitch crunch.

-- The materials seem sufficiently durable, and the fabrics are not too slippery, which I was glad to see.

[ -- Can't speak to warmth (yet) ]

-- When deflating, you will be thankful for the horizontal baffles: it makes it a snap to get all the air out of it. Much easier than vertically-baffled pads.

-- Folding the pad (lengthwise, in thirds) made it easy to compress back to its original size (and maybe a bit smaller).

-- It might be preferable to roll up the pad at its full width, making for a long thin object suitable for packing. Certainly easy to do.

Can't wait to use this out in the field. I have a feeling I'm going to be pretty happy!

This is the size large Xtherm, just out of the box. To my amazement, it packed up a little smaller after I had inflated it and repacked it!

Weighs nothing!

  • Familiarity: I've used it several times

I picked this up over the summer and could not believe how light it was, there was nothing to it! That aspect alone makes it the perfect backpacking pad, and on top of its next to nothing weight it is actually comfortable.
When I first tried it out I remember thinking it was going to be really annoying because of how much it sounded like a plastic grocery store bag. It's not as bad with a sleeping bag on top of it, and you can't be this pad for a lightweight backpacking pad.
I am 6'3" and it was long enough for my as well.

The Best of the Best

  • Familiarity: I've put it through the wringer

I?ll preface this review with my cut and paste statement that I work as a backcountry backpacking guide in Yosemite National Park. Nearly all of the products I take the time to review have seen at least a half a season, if not more, of use... and I?m committed to not bothering to write a review until I feel like I?ve really gotten to know a product. I never thought I?d bother to write reviews, but I?ve recently decided that since I?ve spent so much time over these last many years reading reviews, and finding a tremendous amount of value in articulate and well-informed opinions, that I wanted to give back to the community. So, with that being said, here we go.

When I bought the very first generation of NeoAir (the old lemon-lime rectangular one) I knew I had found my sleeping pad. I've put nearly 300 days on that pad, and finally retired it because its looking really old and worn. It still works perfectly. I replaced it with the new generation NeoAir XLite.

However, earlier this year I had a winter climbing trip to Yosemite Valley for a week, and my climbing partner and I were going to be sleeping in the snow in Upper Pines campground. I have a Western Mountaineering Antelope that would prove to be plenty for the single digit nights... but I was a little worried about my first gen NeoAir, which has a R-rating around 2. So I decided to pick up the XTherm.

First night in the valley it was around 5 degrees. I awoke in my beloved GWS Antelope (which is rated at 5F) and was absolutely roasting. I was very aware of how much warmer my back was than my chest. The XTherm immediately won my heart. I had to keep my bag ventilated all night because of how warm I had gotten.

Given my experience with NeoAir pads, and now with the XTherm, I can honestly say that, in my opinion, they are hands down the best sleeping pads around. They are supremely lightweight, very, very durable, and incredibly comfortable. I can't imagine ever trusting other sleeping pads with my sleep.

NeoAir X Therm Sleeping Pad

  • Familiarity: I've put it through the wringer

I have 3 other Therm-a-rest pads, all self inflating. I bought the NeoAir X Therm to use on a bicycle tour on the Pacific Coast Highway through Oregon in August 2013. I also bought the air pump designed for this pad. I can say, honestly, that this is the best thing to happen to sleeping pads ever. I slept well each night, my butt was never on the ground the next morning and best of all I didn't wake with a cold back. The Oregon coast can be chilly at night, I used my sleeping bag as a quilt ever night because this pad radiates body heat right back to where it started. I love this pad and will use it for my Mountaineering trips this winter. I am thinking, I will not need, a closed cell foam pad with the NeoAir X therm Pad. The pad was easy to deflate and easy to roll up and put in it's stuff sack. I also purchased the air pump that will inflate this pad, 2.5 ounces. I was on tour for 15 days and there was no issue with battery life. This pair of sleep equipment will go on all my trips....

Love this pad.

  • Familiarity: I've used it several times

I've used it a few times at high elevation, 10,000 feet, and have been comfortable and warm. I use a down sleeping bag that I basically have unzipped every night because the pad is so warm. Blowing it up is ok with the mouth but the bag they give you to use to blow it up is a joke. I have a singelist that is nice to pump up without blowing but I find it looses air in the night vs my neoair stays full the entire night.
