Thermarest Z Lite SOL

 Both the Z Lite SOL and the original Z Lite feature a compact accordion-style shape and heat-trapping dimples. The Z Lite SOL adds our reflective ThermaCapture™ coating that helps capture radiant heat, increasing overall warmth by nearly 15%. The proprietary foams are softer on top for extra comfort and denser on the bottom for extra durability. Wherever you're headed, a Z Lite mattress is the right choice for ultralight warmth, durability and comfort.
