The Nemo Astro Lite Sleeping Pad is an ounce-counting ultra-light backpackers dream. At just 14 ounces, you're not going to find many inflatable sleeping pads lighter than that. As a result, it's obviously somewhat bare bones and not suited for cold weather camping. But in its element, it shines. The Astro Lite is 3.5 inches thick, provides plenty of comfort from the stony ground, and comes with a pump sack for easy inflation. Of course, it folds up teeny tiny and weighs just a little bit more than no sleeping pad at all.
