Therm-a-Rest Neo-Air Xtherm Sleeping Pad

The XTherm air mattress delivers, by far, the greatest warmth-to-weight ratio available in any air mattress, allowing you to go lighter than ever in winter conditions. Patent-pending ThermaCapture Radiant Heat Technology gives the XTherm air mattress true four-season warmth without the weight or bulk usually found in a winter-worthy mattress. The result is a mattress that weighs less than a pound, takes up about the same space as your water bottle, and provides serious comfort in extremely cold conditions. Pump sack and repair kit included.
