Warmer and more comfortable than ever, the classic Therm-a-Rest Trail Pro Sleeping Pad is your ticket to the Land of Nod in the backcountry. This classic has been updated with diagonal-cut foam, which brings added warmth by minimizing convective heat loss. Sleeping comfort is boosted by body-mapping construction that delivers targeted support and softness where you need it most, so you're sleeping far better than you ever thought you could on a two-inch thick pad.
