Stay Fast and Light.

Fit for royal prestige, the Therm-a-Rest Trail King SV Sleeping Pad ensures you're able to get the beauty rest you need in order to tackle a full day on the trail.  Merging comfort with lightweight dependability, the Trail King SV features Therm-a-Rest's AirFrame technology, which offers 2.5-inches of supportive and cushy loft. More importantly, though, the Trail King is equipped with a SpeedValve, which inflates (or deflates, for that matter) the sleeping pad in what seems to be a blink or an eye: simply unpack the mat, lay it flat, inflate the mat, and roll the valve shut seven times and buckle it closed to prevent air from escaping overnight.

  • A lightweight sleeping pad that's ideal for backpacking
  • 1.8 R-value offers three-season versatility
  • Speed Valve provides quick deflation and inflation
  • Stuff sack included for your convenience
  • Item #CAS00AW
