The NEMO Cosmo 25 Sleeping Pad is a 3.5 inch thick pad for cushioned sleeps in the tent. The cold, hard ground isn't comfortable, so stay off it and sleep on one of these instead. The integrated foot pump makes it quick and easy to inflate, plus won't burn out your lungs. Features of the NEMO Cosmo 25 Sleeping Pad The integrated foot pump is fast and efficient, and vastly superior to using your lungs, especially after a day on the trail Lateral baffles Are less noticeable than vertical baffles, which align more with your limbs Plus lateral baffles prevent the pad from curling under your weight The Oversized pillow baffle at the head end provides extra loft under your head and prevents your camp pillow from sliding off the end
