Rest in comfort and warmth thanks to the Triangular Core Matrix™ construction and ThermaCapture™ Barrier technology. All that body heat just reflects right back at ya through the night.

Rated 5 out of 5 by from Great sleeping pad Great comfort and love the speed of setup and break down. Held air fine and and had no issues. Used a stuff sack to inflate then just unroll the big valve and roll back up.

Rated 5 out of 5 by from warm and quiet Was excited with the color, my fav. Inflated mattress and fell asleep on it. I was warm and did not have a blanket. I like the design. Inflates and deflates quickly. Goes back to sack size faster than any mattress i've owned. Will be using it winter camping in Ely, MN in January. Let you know more then!

Rated 5 out of 5 by from Best sleep in the backcountry! This is hands down the best sleeping pad I have ever had. I read reviews how people are having issues with inflating the mattress. Nevertheless, I still decided to take it with me on my recent long-distance ride from Mexico to Canada. To simply put it, if you use a dry bag, then you can use this sleeping pad. Because let's face it. If you can't close up a dry sack, then you need to ask yourself what you're doing in the backcountry in the first place. I love love love this pad!

Rated 5 out of 5 by from Best night of sleep in years!! This is my first inflatable pad purchase after using my ole' trusty RidgeRest foam pad. After years of poor quality sleep on backcountry excursions, this was my best night of sleep yet!! I also really like the speed valve for ease of use. Thank you Thermarest!!

Rated 5 out of 5 by from Well worth the investment Super comfortable mattress. Has held air very well over the past two weeks while on a fire assignment in Montana.

Rated 2 out of 5 by from Think twice.... I bought this in HK and was so relieved to find a soft underlayer for our outdoor camping trip. The inflating was quite a challenge. But when inflated it was the right thickness and v comfortable. However as it deflated every few hours, we got up three times over a very miserable night to blow it up each time. And as it made so much noise every time we moved, my husband and I woke each other at every turn, every moment of inflating the bed again and every time we clambered back to bed. It was almost comical! We were not happy campers as sleep became impossible.

Rated 4 out of 5 by from Very Nice Mattress As long as you don't mind very bright green, then this mattress is for the most part very good. Like other Thermarest mattresses, they seem to lose air overnight. The trick seems to be to try not to put any full direct weight on one specific area of the mattress (like sitting up) prior to sleeping and most the air inflated with will keep the night. This All Season mattress is very warm during colder months. The exterior material is very durable and strong to the touch. The size large was a bit longer than expecting. As for the smart valve, it's extremely useful for fast deflation to pack up and can significantly cut inflating time in half as well. The compactness and lightweight construction of this mattress is quite amazing. Not too fond that the bottoms of these mattresses are no longer a darker fabric like in the photos (they are all one color now). This color green is very bright for my taste but other than that is overall a pretty awesome mattress. 4.5 stars if I could rate it such for quality construction.

Will cold temperatures crack the material? What is the lowest temperature it will tolerate before cracking?

Asked by: Gramma
Hey there Gramma, According to Therm-a-Rest, there isn't really a risk of cracking in cold temperatures. The only thing that might affect it is if you are inflating an air mattress with your breath in below zero temps. The moisture from your lungs will hang out inside the mattress and freeze, causing the mattress to become heavier and moisture to live inside the mattress until things warm up and it can evaporate. Thanks for your question, and hope this helps!
