Some pads are made smarter than others. The Kelty PDsi Self Inflating Sleeping Pad is part of the TrailLogic™ Collection and designed to help you get more comfortable naturally. With an innovative bio-mummy shape for extra lightness and bio-mapped insulation that follows the human form to boost warmth, this pad is miles ahead of the rest. It’s also free of PVCs and comes with a convenient carry cube stuff sack. Every camper could use more under-the-bag intelligence.
