The Cascade Designs Expedition sleeping pad was the winner of the Backpacker Magazine 2003 Editior's Choice Awards, and "it employs the best combination of comfort, warmth, and weight." Made with 1.75 inch open-cell foam, the Expedition comes in three sizes that fit various body types and sizes. New die-cut foam reduces volume and weight, making mattress even more packable than the original Therm-a-Rest Standard, and the non-slip bottom keeps pad from sliding around, for all-night comfort. Chair kit (sold separately) adds comfort around the camp. This is the best all-around, self-inflating mattress: it's light enough for backpacking yet comfortable for car camping.
