By combining our SpeedValve technology with AirFrame Construction, we've created a backpacking mattress that inflates in a matter of seconds. Plus, thanks to the auto-reversing SpeedValve, the mattress deflates at remarkable speeds. This unprecedented ease-of-use is fused with 2.5 inches of ultra-supportive loft and an R-Value of 1.8, making the Trail King SV a reliable and three-season mattress designed to save you precious time in the backcountry. Stuff sack included.

  • Supportive Loft: AirFrame construction offers 2.5 inches (6.3 cm) of high-loft support.
  • Fast Inflation: SpeedValve technology combined with self-inflating foam creates swift inflation.
  • Faster Deflation: Auto-reversing SpeedValve deflates mattress in a flash.
