Campsites on hard-packed dirt and stones in Idaho’s Sawtooth Mountains felt like a feather bed with this inflatable mattress, which has nearly three inches (seven centimeters) of cushion, but still weighs less than many competitors and packs down to the size of a liter bottle. It takes me about 18 puffs to blow it up, and with separate valves for inflating and deflating, there’s no leakage when inflating and it deflates in seconds. The synthetic microfiber insulation translates to warmth even in temperatures several degrees below freezing (assuming an adequate bag, of course). I found the mini-pump made for the pad—useful to avoid blowing moisture into the pad, which can freeze on cold nights—to be slow. It’s pricey, but nails perfect scores for comfort, insulation, low weight, and compactness.
