Rated 5 out of 5 by from warm and comfortable This has been one of the best purchases I have made (used my 20% off). I bought this mainly for late season solo elk hunting. I needed something that was warm, packed small, and was lightweight. I used to pack a basic therm-a-rest + foam pad but I wanted to save on bulk and weight. The XTherm has served me well. A little noisy, yes, but nothing obnoxious and it is extremely comfortable and warm. I swear I can feel the heat reflecting back to me. It works well in both summer and winter, I have even used it in the house when sleeping on the floor next to a little one who was sick on the couch. I have no regrets with this purchase.

Rated 5 out of 5 by from Excellent pad but beware I have both a regular and long of these for our family. Works great - Fills Quickly, very comfortable. Two consideration. The regular is very narrow such that I'm 5'9" and when on your back your elbow hit the ground. So you can either side sleep all the time, or place boots under your elbows but it's really uncomfortable. The long is much more comfortable to sleep on but is heavier. Also inflate the pad all the way so it's firm. If you have it soft, it CRINKLES like you wouldn't believe and would drive the animals in a stampede and your campmates crazy. FIll it firm and it's quiet.

Rated 5 out of 5 by from Totally awesome I and three of my Aussie mates have just returned from 4 weeks on South Georgia Island. We were privileged to obtain permission to circumnavigate this remote island in the South Atlantic by sea kayak. 2 years of preparation went into the trip and we decided on the NeoairX-Therm mat. We made camp each night on some of the rockiest harsh terrain that we have ever camped on. We were buffeted by 50 knot wind, sometimes freezing temperatures..... and I have never slept so well. This mat is truly awesome. it packs down so small that we carried it in our carry on luggage and slept in airports in the Falklands and Punta Arenas without a care. Thanks Cascade Designs!!!

Rated 5 out of 5 by from Light weight and durable! Bought this sleeping pad about 2 years ago. The weight and durability of this pad are amazing! The cost is high, but worth every penny. I have used this sleeping pad on 5 separate backpacking trips in the past 2 years that lasted between 3 to 7 days. Each trip had different weather conditions between summer, spring and fall seasons. I was worried that the pad would be too warm in the summer trips. I had no issues with over heating in the summer nights and it works great on the colder nights! I am 6'-0" tall and about 185 lbs. The regular size fit me well, even though I tend to sleep on my side. I would recommend anyone taller or larger than me go with the larger size.

Rated 5 out of 5 by from amazing I purchased this pad a few weeks ago and I'm glad I did. I'm 5'7'' 155lbs and decided to Purchased the large size. I'm a stomach sleeper and noticed my shoulders hanging off the sides with the small pad. The large, in length, is much greater and touches both ends of my Big Anges Fly creek HV UL2. The complaint about the pad being noisy was not an issue at all. When properly inflated, the pad is quiet and my sleeping bag muffled any additional sound. The other campers never complained of any noise from my pad, and I move around a lot at night. This pad is warm, you can feel the heat reflecting back at you. Overall, if you can afford it and you take care of it, this pad is worth every penny.

Rated 5 out of 5 by from Warm and Compact! I purchased the regular size pad hoping to save a few inches from the longer version and it fits perfect for my slender 6'2" body (My entire body fits with a couple inches to spare). I was attracted to this product based on its packed size (Easily 6" tall by 4" wide). I have used the pad during cool nights and was glad to have the extra warmth from the thermal material. The pads width is thin so your arms may hang over a bit; this wasn't a huge concern because I tend to be a side sleeper. For the side sleeper the pad was plenty thick (about 2 1/2") to keep you supported and comfortable. The pad comes with two stuff sacks; one that is used to inflate the pad (I also use it as a pillow), and the other is a small sack that everything packs into.

Rated 5 out of 5 by from 2.5" pads are the new black/this is THE One. I have camped the southern 813 miles of the Pacific Crest Trail sleeping on the XTherm, either on a Tyvek groundsheet or in my hammock. I've not had a cold night yet from the pad not insulating. No issues for me as a side sleeper. The inflating stuff sack works well. No durability issues surfaced. Minimal noise for me. Just a great pad after all the years of suffering lesser products. Only one fear haunts me: when will it leak? And will the repair kit still be effective then?

Rated 5 out of 5 by from Comfortable and warm Purchased last year (2015) based on reviews and am not disappointed. Very comfortable and warm compared to previous generation pads and so much lighter and smaller. I have used it on a week long backcountry trip in the Olympics in summer and a long weekend in the Rockies in September at tree line. Both times I used a 3 season quilt (Catabatic). At 30 degrees I felt no cold coming through the pad. I was concerned about the crinkly noise but in practice it has not been a problem. It is horrendously expensive for a pad but it you want the best and can afford it, go for it! The thermarest chair however does not work well, the pad pops out of it at irritatingly short intervals. I returned it and will try another brand.

I purchased this the other day, they didn't have the non-speed valve x-lite model. Would this be overkill for Arizona hiking, with the higher R-value? The 3 oz. difference is making me question this one also, as I am looking to cut weight.

Asked by: Theresa
This is my all-weather pad. Sure it's got a high R-Value.. but I found it fine in summer months. With a bag/sheet between you and it, you're golden in all 4 seasons. I thought about getting a summer-only pad, but the minimal weight and the comfort of this pad just make me keep with it, all year, every year!

I have seen on Therm-a-Rest's website that this pad is updated for 2015. Is this the updated 2015 version or a previous version?

Asked by: LightweightHiker23
The NeoAir XTherms that we have in stock are the most recent versions.

Can I dispense with the formality of folding by three lengthwise and then rolling toward the stem and just stuff it in its bag or some compartment of my pack, valve end last?  Time saving on thru-hiking.

Asked by: Lavrentii
We recommend spending a little extra time to roll this up properly to maximize the security and protection of the pad during transport.

What is it that gives this such a higher R-value than the Xlite model?

Asked by: Lew Fisher
The NeoAir XTherm has more insulation compared to the NeoAir Xlite which gives it a higher R-value.

I'm looking to purchase this pad but now find myself concerned with durability. Has this issue been addressed since 2015?

Asked by: Wildernessman
The pad was updated last year and feedback suggests it is more durable than the original model.

I am looking at this pack for all seasons, I am worried about it being too hot in the summer. Have you gotten any feedback on that?

Asked by: jamierose
The NeoAir XTherm Sleeping Pad provides plenty of insulation for winter camping. We have not heard any feedback about it being too hot for summer camping.

Can this pad be kept rolled up for storage, or is it better store it slightly inflated?

Asked by: HaJo
Therm-a-Rest recommends storing the NeoAir XTherm sleeping pad deflated and rolled in a stuff sack to protect it from dirt and sharp objects.

does anyone know if this will fit in big agnes roxy ann sleeping bag?

Asked by: rikkka
This version of the NeoAir XTherm is not recommended for the Roxy Ann. This pad is more of a mummy style shape which can cause cold air from the ground to get inside of your sleeping bag.
