The Thermarest Trail Pro Regular Wide is a 4 season, self-inflating backpacking mattress that offers huge warmth and comfort when on the trail.
If comfort and ease-of-use are top priorities in your backpacking mattress, the Thermarest Trail Pro Regular Wide camping mat should be at the top of your list. The warmest and most comfortable self-inflating camping mat features an exclusive ultralight foam, saving you weight and space in your pack without any sacrifice in comfort. Added air bolsters also shave precious ounces whilst allowing the mattress four-season warmth. A semi-rectangular shape increases sleep surface area and offers better gap-free mating of mattresses.
