    Made for winter camping.

    On your next winter camping trip, enjoy the highest warmth-to-weight ratio of any Therm-A-Rest air mattress by using the NeoAir XTherm Sleeping Pad. This lightweight pad insulates and cushions you from the hard, frigid ground below without tacking on the weight or bulk normally found in winter-worthy sleeping pads. ThermaCapture layers within the pad keep you toasty by efficiently insulating and reflecting heat back to your body to keep the cold ground from sucking away all your precious warmth. As you toss and turn, the durable materials resist jabs from rocky campsites, while the soft, no-slip top fabric boosts comfort and keeps you from slipping off your pad when you're sleeping on uneven ground.
    • Lightweight pad for cold-weather trips
    • 5.7 R value is suitable for winter camping
    • Ripstop nylon resists punctures
    • ThermaCapture layers trap air and reflect heat
    • Mummy shape shaves ounces off
    • Item #CAS002O

    Warm and Noisy

    • Familiarity: I've put it through the wringer

    I've used this pad over approximately 35 nights in the Sierra Nevada.
    Pros: It is extremely warm. The relatively high r-value of the pad is noticeable. It has kept me toasty with my 20F mummy bag in temps down to 14F. It does a great job of covering up rocks in the event of poor campsite selection. I've used it on granite slabs and didn't notice I was sleeping on rock. I'm 6'3" and have the long version. It is the perfect length for me. I also love that it packs down to a bit smaller than a Nalgene bottle.
    Cons: This pad is loud. My tent and camp-mates almost always remark on how annoying it is to listen to me during the night. Usually I respond by suggesting they find a pad as comfortable as mine. In their defense, I am a side-sleeper who tends to move around a bit during the night, which brings me to my only real complaint. I wish this pad was a bit wider. I do find that I sometimes get the "falling off the bed" feeling in the middle of the night, if I'm not centered on the pad.

    Quality Pad Best Used for Ultra-Light

    • Familiarity: I've put it through the wringer

    I used this pad last summer while camping for work in Central Asia. I wasn't able to test it in extreme cold temps, but on really hard ground it provided great padding, and the no-slip surface was great to have so that my bag didn't slide off all night, which has been a complaint I've had with other pads in the past. It takes a few minutes to blow up manually (bribe your friend to help and it goes easier), but I found that getting it almost but not completely full keeps your hips from hitting the ground but means that you don't slide off it from it being over-full.
    My only two complaints with it are these. It is a bit loud (as others have mentioned), which is less of an issue if you are bone-tired, but still if you can't get a good night's sleep when you need one could be an issue. Secondly, for a tall person (I am almost 5'11"), I found that the mummy shape meant it was so hugely tapered that all night whenever I changed position my legs from the hips down would fall off or my upper body would start to drift off at the hips, and I would have to bodily lift myself off to re-position in the middle of the pad, working to get my sleeping bag re-adjusted and in place because of the friction provided by the no-slip surface of the pad. To give you an idea dimensions I was dealing with: I'm 5'10" and 140 lbs so when lying flat I still have space on the pad.
    I would say if you don't really move at all in your sleep, or if you are packing into the backcountry and need to really cut down on your weight, this is a great pad to consider. If you are riding/driving, have a sled, or are going by water craft (kayak, canoe, etc), and if you are tall or move when you sleep, I would consider a wider pad.


    • Familiarity: I've used it several times

    This pad is amazing! I used it winter camping a number of times and it kept me quite warm! As others have noted it is a bit noisy, but for those of us who sleep like rocks, it isn't too much of a problem.

    It's incredibly light for what it offers, packs down to almost nothing, and should be the first pad you reach for for winter camping.

    The only person I wouldn't recommend this too is someone who moves a lot in their sleep and has trouble getting to and staying asleep simply because of the noise factor.

    Warm & lightweight, but noisy and narrow

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

    I bought this as a gift for a friend and here's what he had to say: I chose this for it's high R-value, to bolster the warmth of my sleep system, for which it does deliver. The pad is not uncomfortable, but crinkles loudy if you fidget too much, and a bit narrow, so perhaps not great for a restless sleeper. In winter those seem minor compromises for the warmth it delivers, for more temperate trips, I'll look for something wider and quieter.

    Catch Zs, Not A Breeze or Roots of Trees

    • Familiarity: I've put it through the wringer

    With the Therm-a-Rest NeoAir XTherm, you will be catching Zs all night long. Never once will you be woken up in the middle of the night feeling the cold of the ground conducting through the compressed insulation of your sleeping bag onto your back. Never once will you go to bed exhausted from the trail, only to be woken up hours later with a sore hip on the ground due to the air in the pad cooling and compressing. The days of a bad sleep in the backcountry are over. The NeoAir XTherm is simply the best air pad on the market. With an R-value of 5.7 quilters will laud the warmth supplied by the pad, and side sleepers (as myself) will never wake up again with their hip on the ground. The 2.5 inch thick pad is thick enough to be able to let some air out of the pad to really dial in the comfort and sleep on a cloud. The internal horizontal baffling of the XTherm is genius - the pad doesn't bounce around like an air mattress when shifting weight. I'm 6'2" and I got the Long size so that I wouldn't have to put my pillow off of the pad - great decision and well worth the extra 2-3 ounces. The pad is definitely louder than probably other air mattresses, but it's never been an issue to fall asleep for me in the 8 times that I've used it. Can't put it any more plain - if you are tired (pun intended) of not getting a good night's sleep in the backcountry, order this pad. It will change your whole view on how great sleeping in the backcountry can be.

    All Around Great Sleeping Pad

    • Familiarity: I've put it through the wringer

    Agree with others who have mentioned how noisy this can be when you're shifting around. If you're a heavy sleeper like me, it won't be an issue – can't always say the same for anyone sharing your tent. Super light, packs down small, and well made. A little slippery – I tend to be a side sleeper and sometimes I'll wake up to find that I've somehow slid completely off this pad. Overall, a great sleeping pad.

    Exceptional piece of equipment

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

    Went to kirk creek campground at big sur on december 2017 and the temperature dropped to about 4 degrees celcius at night. I couldn't be happier with the warmth and comfort this pad provided. Super lightweight and packable as well! My buddy who was sleeping in the tent next to me could hear the crinkling sound from the pad. If a noisy pad annoys you or is a factor of consideration, i would recommend to stay away from this pad. Otherwise, if you are a thru hiker and is looking for a lightweight and comfortable pad, i would highly recommend this pad.

    Cream of the crop

    • Familiarity: I've used it several times

    Great pad that's very light and packable, it was very comfortable and warm on a September backpacking trip which included 8 days of snow. There's nothing else out there that offers the warmth and function of NeoAir XTherm!

    Do it all

    • Familiarity: I've put it through the wringer

    I use this pad for everything. It has the best warmth to weight ratio of any pad on the market, and is just a few ounces heavier than the Neo Air, which makes it pretty competitive backpacking as well. Due to the great R factor I can carry a lighter bag all of the year than I normally would, which more than makes up for the ounces I gain with the heavier pad. It is very noisy, so when weight isnt an issue I carry a pad fitting sheet. Other than the noise, this pad is great.

    Ideal winter pad

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

    Is as described, only note is I'm a little paranoid the crinkling while moving may annoy others in the tent, but I'm warm, and it's light as crud for the R value!

    The pad I take when I sleep on snow

    • Familiarity: I've put it through the wringer

    I used the pad my first time without a closed cell foam underpad and learned the hard way that you need two pads to sleep on a cold glacier, was I miserable? No, though I could still feel the cold creeping up from underneath me. Once you add a thin closed cell pad on the snow and then this thing on top of that.. Yeah, that is the way to go.

    I am also a side sleeper, I find I toss and turn all night long trying to get comfortable. I have heard it said that a good climber is someone who can make the best out of adversity. This pad is OK and is better than your standard lightweight pad, can I say it is going to give you a comfortable nights sleep? No, I can't, for a warmth to weight ratio it is better than what I have used in the past, but I can't say i have found a lightweight and super comfortable combination, from the crinkly noise to what feels like a balancing act to keep on top of it while I toss and turn.

    I would recommend it, but I also look forward to what someone can come up in future years that will be more comfortable, while still keeping the weight and warmth ratio this thing has.

    Heavy use through Utah winter

    • Familiarity: I've put it through the wringer

    This is a lightweight compact sleeping pad that works wonders through the winter. The color is accurate to the website, it's a light grey throughout. One concern I had initially was the sound of the pad while sleeping on it, once I got it into the field it was not a problem. Because you will most likely use this in the winter I had a large down sleeping bag that blocked out most sound from the pad. It really doesn't make much noise anyways. The pad feels like it's actually warm on the top. What I mean by this is that while you sleep on it your body heat and sleeping bag heats the top of the pad. I spent many weeks through the winter sleeping in snow and temperatures that hovered around 0 degree F throughout the night and never felt I was sleeping on a cold pad. If you have any plan to be in extended cold climates and are looking for a pad this is one of the best investments I can recommend.

    Best Night Sleep on the Trail

    • Familiarity: I've used it several times

    I have slept on a couple of different type pads (cheaper ) and always tossed and turned all night, waking up in pain. Sore hips and shoulders. So I decided to spring for a little better pad and have never been more happy. I sleep comfortably thru the night. It is a little noisy but since I'm so comfortable on it I don't move nearly as much therefore less noise.

    Awesome Pad

      This pad is great because it's light weight so you can backpack with it, and its also super comfortable. It is worth it to splurge on a good sleeping pad especially with Therm-a-rest because in my experience they're more durable then other inflatables out there.

      I'm Sold

      • Familiarity: I've put it through the wringer

      I don't buy into hype when choosing my gear! I check several sources I trust when I review a product. I trust Outdoor gear lab on all their top choices except when they jumped on the North Face GTX 109's(they suck) other than that they've been spot on. After reading reviews on multiple retailers sites on some of the complaints, noisy , bad for side sleepers, uncomfortable, went flat on multi day trip. I needed to lighten gear to 20-25lbs pack I had to give up my comfort set up cause I was always carrying 35 lbs+. Upgraded tent Zpacks Duplex, Pack Gossamer Gear Gorilla & HMG Windrider 3400 on wet trips, Bag enlightened equipment revelations 20, pad you guessed it this one. I addressed complaints Noisy I can live with or have you, your girlfriend or wife wear earplugs Not good for side sleepers & uncomfortable I found deflate the pad so low that when turn on your side your hips barely don't touch the floor! This solved all the uncomfortable issue even sleeping on my back is way more comfortable now! The complaint about going flat on a multi day trip! Dude those are the risks of an air pad you take your chances or go close cell or utilize the patch kit. For weight, warth & comfort "I'M SOLD"! My Backpack weight average is now 15-20 lbs . I spent a lot of money, was it worth it? Yes I can go on butt kicking trips, high elevation & not die ! it's worth every penny! Thermarest Neoair Xtherm my body thanks you!

      Unanswered Question

      Is the NeoAir model the same as the NeoAir Xtherm? Thought I ordered the XTherm but only labeling on the product is NeoAir

      Is that 4 seasons sleeping pad ? Is it self inflating ?

      Is this out of stock again since James's inquiry? or have you not gotten the expected shipment from 3/23? At any rate, when will this be in stock again?

      Hey Jon,

      Unfortunately we're still waiting on our shipment from the vendor.

      Sometimes they come in on time, other times we have to wait a bit longer.

      Shoot me an email if you'd like me to notify you when they come in stock.
