Thermarest NeoAir XTherm Sleeping Pad

  • Product Number: 1448

The NeoAir XTherm is one of Thermarest's warmest, most comfortable mattresses.  With an R-value of 5.7, it can tackle camping in any season.  The reflective barriers throw heat back at you for 4-season warmth without the weight or bulk usually found in a winter-worthy mattress.  The result?  The NeoAir XTherm weighs less than a pound, packs smaller than a water bottle, and provides some serious comfort when you're crashing at the end of a day playing outdoors.


  • Extremely Warm: Four layers of reflective material recycle body heat and create air pockets that reduce convective heat loss.
  • Comfortable: 2.5-inch 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.
  • Pump sack and repair kit included.
  • Made in Seattle, USA
