Gear Review: Therm-A-Rest NeoAir All Season mattress

Therm-A-Rest NeoAir All Season air mattress

Insulated Winter Air Mattress
Therm-A-Rest NeoAir All Season mattress
$150, 1 lb. 3 oz. (reg)
Sizes: M 20x66x2.5 inches, regular 20x72x2.5 inches, L 20x77x2.5 inches

I spent three January nights sleeping under the stars in the Boise Mountains on this air mattress (in a 0° bag) and stayed perfectly warm in temps down to the low teens, thanks in part to the NeoAir’s high R-value, or ability to insulate against the frozen ground. Impressively light and compact for an all-season mat (only slightly larger than the Exped SynMat UL 7), it employs more than 100 internal cells to trap warm air. Two-and-a-half inches of thickness also delivered nice cushion on ground littered with small stones during a four-day, early-autumn backpacking trip in Idaho’s Sawtooths. The mat can be inflated directly without concern for moisture from your breath freezing inside it; I found it took about two dozen puffs of air.

Another favorite winter air mattress, the Big Agnes Hinman, is less than half the price, but also about twice the weight and more than twice as bulky as the NeoAir All Season. Looking for an ultralight air mattress for three-season camping? See my review of the Therm-A-Rest NeoAir XLite air mattress and Z Lite Sol foam pad and my review of the Exped SynMat UL 7 air mattress. I also never sleep outside without my Cocoon Ultralight AirCore Pillow.
