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.
