These days, lots of sleeping pads are marketed to make them sound like the next NASA project destined for outer space. Xtreme-thermal this, r-value that, yada yada. Well if you ever want to come back down to Earth for a good night's sleep under the stars, pick yourself up a Thermarest Z Lite pad. As the name implies, it’s light, and it folds up like the letter Z, and there ain’t much more to it. It’s made out of foam, so it won’t pop without a moment’s notice, and it’ll probably last longer than any other piece of gear you own. $55.
