Designed for couples, the Exped DeepSleep Mat Duo 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. Its oversized dimensions offer plenty of room for two to sprawl. 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 Duo 7.5 is available in Medium (72' x 40.9' x 3') and Long/Wide (77.6' x 52' x 3') size options. A stuff sack is included.
