WHAT IS IT? The Thermarest NEOAIR® XTherm™ is a light weight 4 season air mattress. It has the greatest warmth-to-weight ratio of all air mattresses on the market. With an R-Value of 5.7 and a total weight of 15oz / 430g in the regular and 1lbs 4oz / 570g in the Long.
WHO IS IT FOR? Anyone going on single night trip to a longer expedition in any season will be happy with this mattress. The ultralight mountaineer will be happy with the warmth-to-weight ratio.
PROS: We used this pad on our 26 day Denali expedition, with some nights as low as -20 the mattress kept us warm throughout the night. The compact size made for packing in an already large pack much easier and less bulky. The large valve made inflating the mattress a quick process even at 17k ft where the air is thin.
CONS: I honestly can’t think of anything that could be improved in this mattress.
OVERALL GEAR RATING: 5 out of 5 I love the weight and warmth of this mattress.
IS IT IN MY PACK? Without a doubt on any overnight trip I go on it is my go to mattress.
