SitPad Flex is a rapidly deployed, lightweight, surprisingly comfortable and versatile closed-cell foam sit pad. The low profile, 3-panel design fits in side-pockets or mesh panels of backpacks and bike bags. Works well as a cushion on a kayak or canoe seat and as insulation in lightweight backpacking chairs. Excellent insulation for sitting in a snow-kitchen, on a beach or a hard stadium or picnic-table bench.
