    Made for winter camping.

    Get the highest warmth-to-weight ratio of any air mattress on your next winter camping trip with the Therm-A-Rest 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.

    Tough nylon can handle sharp 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. ThermaCapture layers within the pad insulate and reflect heat back to your body to keep the cold ground from sucking away all your precious heat. The mummy shape saves valuable space in your pack and shaves down weight.

    Worth the price tag

    • Familiarity: I've put it through the wringer

    Used this for over 30 days in the backcountry and gotta say I really love it. I'm tall, 6' 2" and bought a large pad. It's warm enough for winter camping up in the boundary waters and light enough for summer backpacking trips. As for people saying it's noisy, I've never encountered the noise to be too loud to disrupt my sleep. I also love this pad because I don't slip around on it as much as on my old REI pad. It comes with a stuff sack that doubles as a pump. I have the "Compak Chair" adapter that turns this into a chair, making it a wonderful item for lounging on during less intensive trips. It's durable to last through so far 1 year of abuse. I literally have no complaints with this.

    Great buy

    • Familiarity: I've used it several times

    I love this pad. It is just as comfortable as my bed. It does make a crinkle noise but it is worth it. It is much quieter with the sleeping bag on top. The comfort is heavenly. If you move lots in the night people will know. I could feel the warmth immediately. I bought a large I am 6'2 191 lbs glad I did. Thanks backcountry!

    My first Thermarest

    • Familiarity: I've put it through the wringer

    I'm familiar with several styles of inflatable mattresses, but this is my first Thermarest. I was pleasantly surprised at the speed at which the pad filled with air, only taking a handful or two of breaths to top off. I've slept on sand, gravel, cobblestone, and snow in this pad and have always been able to find comfort and warmth. I'm 6'4" and thus far have been comfortable on the standard size, and the pack down size is extremely impressive! Definitely smaller and lighter than other pads that I've used that definitely didn't shield from cold like the Xtherm.

    My first Thermarest

    Thermarest nails it again

    • Familiarity: I've put it through the wringer

    I've used various thermarest models over the years and put them through the wringer. This pad packs down so small without sacrificing ANY R-value. In fact, it is the lightest AND warmest pad I have used.

    The inflator bag is great for keeping moisture (and in turn frost) out of the mattress in those really cold environments, but is also just super convenient and makes blowing it up easier (avoiding the light-headedness).

    Bottom line, whether you're sleeping in 70°F or -40°F, this pad will keep you comfortable, will be a staple of your kit for years.

    Thermarest nails it again

    Amazed by this pad!

    • Familiarity: I've used it several times

    Took this baby packing this first week of Oct. in the San Juan's and got snowed on. I have never been so toasty warm camping above 12,000 feet this time of year, and with so little weight! Totally worth the cash.

    The best pad that exists.

    • Familiarity: I've put it through the wringer

    This is the best overall sleeping pad that exists on the market right now. It's winter rated, has a durable 70 denier bottom, and is only 15 ounces in the regular size. The comparable summer rated bad (the x-lite) is only 3 ounces lighter and has a less durable 30 denier bottom. I use this pad for all seasons and
    I don't see any reason to get a slightly lighter summer rated pad.
    Because this pad uses strips of reflective material as insulation rather than foam, down, or synth puff, it deflates completely flat and packs down very small.
    Buy once, cry once, and buy this do it all pad from company that produces in the USA. Yes its pricey but totally worth it.

    What more could you ask for?

    • Familiarity: I've used it several times

    Light, highly packable, very warm, and comfortable (quite a bit more comfortable than the old style Thermarest IMO). What more could you ask for (besides a discount - I guess you get what you pay for)?

    I was hesitant to go with the Neoair line for a while because of its reputation of being loud/crinkly. It's a bit louder than a standard Thermarest (like the Prolite series) but it's honestly not that bad, and I'm a restless sleeper. Don't let that deter you.

    Durability remains to be seen, but I wouldn't expect any major issues, presuming you take care of it (don't throw it down on bare rocks for instance).

    Great Pad to Pack Out With

    • Familiarity: I've used it several times

    I've spent so long thinking I didn't need a pad for lightweight overnight backpacking ... So wrong.

    Best night's sleep I've had in a long time. Kept me comfortable, warm and it wasn't overly bulky to carry out.

    Excellent pad

    • Familiarity: I've put it through the wringer

    I used this pad couple of days ago on an overnight trip. The temp is about 35 degree during the night. I feel so toasty and warm throughout the night. I upgraded from the z-lite. I won't even wake up if my dog did not step on me. I would highly recommend this pad to anyone. It's light and warm and durable. My dog steps on it during the night, and I don't have a problem at all.

    Excellent pad

    Best night camping in a long time

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

    I took this out last weekend, I think the temp dropped to around 30F overnight but I didn't wake up until the next morning perfectly warm and comfortable. Just laying on it indoors you can feel your own body heat being reflected back after about a minute.

    Very easy to inflate with the included pump sack; I think it takes me just under 10 pumps to get it to a comfortable consistency. I'm 5'11" and about 22" at the shoulders, so I ordered the large because I heard the reg had rolloff/edge support issues for back sleepers. I was able to sleep on my back and sides without any issues.


    • Familiarity: I've used it several times

    After spending a couple nights out on the pad so far this winter, I'm pretty happy with this pad. It's quite a bit lighter, packs up smaller, and is just as warm as my previous pad. The stuff sack pump is pretty handy too since I usually need one along anyway. There is a definite crinkle noise when moving around on it but that doesn't bother me. Overall I foresee getting a lot of use out this pad.

    absolute best pad

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

    this pad is great, its super compact when you want to store it away in your bag while your on your 50 mile hike. its super easy to inflate, and feels very durable. not only does this pad look good, pack down really small, but it keeps you surprisingly warm in the cold snowy nights. so if you want a warm pad to sleep on, this is the pad for you.

    Climbing Standard

    • Familiarity: I've put it through the wringer

    Nothing really compares with it's weight : warmth : size ratio. Insulates well while camping directly on snow(not necessary to have a foam "buffer" underneath). The aforementioned 'crinkly' noise hasn't been an issue and for an average sized male (5'10", 150lb)there is plenty of room.
    I've used this thing from alpine climbs to car camping for a week along the Alcan. It's been brilliant in every scenario! It really is in a league of it's own. Spend the extra money and you will absolutely not regret it.

    UPDATE: So I punctured my pad and attempted to repair it with the Thermarest Permanent Patch Kit but it kept leaking. Sent it back to Thermarest and they just sent me the updated new one, free of charge! Great customer service, will continue to buy their products in the future.

    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.

    Shoot me an email anytime you have questions!
