A rectangular version of the award-winning XTherm that provides extra coverage for extreme temps and campers with wider torsos, this lightweight pad insulates and cushions you from the hard, frigid ground below without tacking on the weight or bulk normally found in winter-worthy sleeping pads.
Unmatched Warmth-to-Weight: Patent-pending, reflective ThermaCapture technology traps radiant heat while Triangular Core Matrix construction minimizes convective heat loss all without the bulk, weight or durability issues of down and synthetic fills.
Excellent Comfort: 2.5 inches (6.4 cm) of thickness and baffled internal structure provide unrivaled stability and support.
Ultra-Packable: Low-bulk materials make the mattress ultra-compact, as small as a water bottle.
WingLock Valve: Therm-A-Rest's intuitive and dependable valve maximizes air flow for easier inflation and quicker deflation. Wings toggle for one-way inflation to save breath.
