Thermarest NeoAir XTherm Sleeping Pad

The XTherm™ mattress is the warmest mattress in the NeoAir collection, allowing you to go lighter than ever in winter conditions. Patent-pending Reflective Barriers give the XTherm™ mattress true 4-season warmth without the weight or bulk usually found in a winter-worthy mattress. The result is a mattress that weighs less than half a kilo, takes up less pack space than your water bottle, and provides serious comfort in extremely cold conditions.

Pump sack, packsack and repair kit included.

Extremely Warm: Four layers of reflective material recycle body heat and create air pockets that reduce convective heat loss.
Comfortable: 6.3 cm thickness and patent-pending Triangular Core Matrix™ construction provides unrivaled stability and comfort.
Highly Packable: Low-bulk materials make the XTherm™ mattress compact and as packable as a water bottle.
Lightweight: Advanced materials and a tapered design reduce weight without compromising warmth.
WingLock™ Valve: Thermarest's intuitive and dependable valve maximizes air flow for easier inflation and quicker deflation. Wings toggle for one-way inflation to save breath.
