The Exped DeepSleep Mat 7.5 self-inflating mattress provides excellent warmth and soft cushioning for year-round camping and does so at a price that won't break the bank. The mattress's open-cell foam core provides a 3' sleeping base and makes inflation easy. When you unroll the mattress and open the inflate valve the foam responds by soaking up air similar to a sponge absorbing liquid. Once the mattress has inflated you can use add a bit of air by mouth or use an Exped Minipump or other Exped pump accessories all sold separately to top off inflation for a firm surface. For a softer surface you can simply release a little air. Large valves aid in both inflation and deflation. A brushed 75D face fabric is durable and has a soft feel. The Exped DeepSleep Mat 7.5 is available in Medium 72' x 20.2' x 3' and Medium Wide 72' x 25.6' x 3' size options. A stuff sack is included.
