The original Therm-a-Rest NeoAir mattress received an Editors’ Choice Award from BACKPACKER magazine in 2009 for its unprecedented comfort-to-warmth-to-weight ratio. The NeoAir XLite mattress—an evolution of the original NeoAir mattress with tapered design and increased warmth—has been honored with an Editors’ Choice Update Award (2012) for delivering even more performance for six ounces less.
