Why We Like The Ether Light XT Extreme Mat

Somewhere in-between car camping and super lightweight backpacking lives the Sea To Summit Ether Light XT Extreme Mat. While it is packable it really shines in providing comfort and warmth in hammocks and tents. The high R-value combines with a thick inflatable design to ensure we are well rested for tomorrow's adventure.

Can’t wait!

[This review was collected as part of a promotion.] Purchased for winter camping and am VERY impressed by the quality, construction, and comfort after using indoors. Looking forward to putting the 6. 2 R-value to the test soon! I suspect it will be fantastic!

Mattress was heavy, very large folded, and not as warm as a R 9 rating indicates.

[This review was collected as part of a promotion.] I feel that the mattress under-performed in cold resistance and failed related to size and weight.

One sheep, two sheep, Asleep

[This review was collected as part of a promotion.] For the thickness and insulating quality the pad is light enough. I’ve used other thick and insulating pads and their body mapping is nothing like the design of the Ether Light XT Extreme. I do wish it packed down into a bit smaller of a package, but for the comfort is worth the space.

Sea to summit Etherlight Extreme

[This review was collected as part of a promotion.] Unbelievably light. Packs small compared to my prior insulated pad. Very warm! Used in two snowstorms so far and was very warm with a 10 degree sleep system.

I have had no problems

[This review was collected as part of a promotion.] I have had no problems with it. it holds air for days. the worst condition i have used it in was wet ground and high humidity with temperatures just below freezing and i was comfortable but it was cool at times so iam looking forward to trying to find its range. I did place an ensolite pad beneath it for protection but perhaps i would have been more comfortable with the ensolite on top. it packs well without adding alot of weight and i like that it has a little cushion to it so even if it fails and air leaks i will still have some protection beneath me.

Love how lightweight and compact

[This review was collected as part of a promotion.] Love how lightweight and compact this is for an all season mat. Fits great along with my sleeping bag in the bottom compartment of my bag. Easy to inflate with the bag and keeps you warm and away from the ground. Worth the money and definitely recommend.

Just got back from a

[This review was collected as part of a promotion.] Just got back from a third season high country hunt in CO. Spiked out in a hot tent with the new pad. It was warm comfortable and sure seems tough. I would recommend this pad to friends.
