The Therm-a-Rest NeoAir XLite is a three season mattress which packs smaller than a 1L water bottle. It delivers more warmth and comfort per gram than any other three-season air mattress available. This year, new softer fabrics bring better next-to-skin comfort and a boost in durability, all with no added weight. For the discerning alpinist, thru-hiker or backcountry minimalist who's counting every ounce, there is simply no better choice to assure the kind of rest you need to enjoy tomorrow. Stuff sack and repair kit included.
