A backpacking icon, the Therm-a-Rest Original Z Lite Sleeping Pad is ultralight, virtually indestructible, and highly compact. Molded into a system of heat-trapping dimples, the proprietary foams are softer on top of the pad for extra comfort and denser on the bottom for boosted durability. The accordion-style design allows for the Z Lite to be unfurled into a sleeping pad, folded into a convenient seat, or even used a mosquito swatter. With its legendary versatility, there's a reason so many packs on the trail have a Z Lite strapped on.FeaturesVirtually indestructible, the proprietary closed-cell foam provides lasting, economical comfortFolding design is compact and easy to pack1.7 R-Value
