The Thermarest Z Lite SOL builds on the original, with the addition of the ThermaCapture Coating which works by reflecting radiant heat back to the body. Accompanied with the heat trapping dimples, the Thermacapture coating helps boost warmth by nearly 20%. The mattress is constructed using softer foam on the top surface for comfort, with more dense foam on the bottom for durability.
