The Trail Pro is a comfortable and easy-to-use self-inflating backpacking mattress, and is now lighter. Therm-a-Rest added air bolsters to shave precious ounces while keeping the mattress’ four-season warmth. The Trail Pro features the ultralight U.S. sourced foam, saving you weight and space in your pack without any sacrifice in comfort. New this year is a Regular Wide size to maximize width without adding length. Stuff sack included.
