Light and packable for minimalist fast hikes, the Ultralight Self-Inflating mats come in at 1 inch thick with the regular size weighing just over 1 pound. We keep the weight down by using a 30-D polyester and our Delta Core-V vertical coring which keeps body contact areas warmer while still offering great support and packability.
