I like to hike long days when I backpack, so I want the lightest gear that does the job. But I also like a comfortable air mat to sleep on after a 20-mile day. Those objectives of comfort and low weight sometimes conflict. But on a four-day, 86-mile backpacking trip in northern Yosemite National Park in September, I slept just about as well as I do in my bed at home on a Sea to Summit Comfort Light Insulated air mat, which weighs under a pound and a half and packs down to about one-and-a-half times the size of a liter bottle.
