Shrink your camping kit down with this backcountry friendly mattress.

If you want to shrink your weekend camping kit down to backcountry-friendly size, this mattress is the magic you need. Free of the added weight of down or the bulk of synthetic fills, the air mattress uses the high-loft and internal cellular structure of its WaveCore construction to deliver exceptional warmth and support. So pack it up and go forth in comfort— you'll be carrying less and sleeping better along the way.


  • WaveCore construction provides 2x the warmth of uninsulated air mattresses.
  • ThermaCapture technology traps radiant heat to retain warmth.
  • 2 inches of loft and horizontal baffles maximize support.
  • Tough, 75D polyester lasts for the long haul.
