These Therm-a-Rest innovations boost the effectiveness and comfort of traditional, flat closed-cell foam pads with heat-formed peaks and valleys. The RidgeRest uses a conventional wave pattern and the Z Lite delivers maximum compactness with a nesting waffle pattern. Both increase dead air space in the "valleys" beneath you to boost warmth, while the peaks maintain support and comfort. In addition, all but our RidgeRest Classic mattress combine these benefits with a dual-density construction that combines a denser, more durable foam on the bottom and a softer, more comfortable foam on top for lasting comfort.
