The Trail Pro from Therm-a-Rest offers four-season warmth and comfort. The 7.6 cm thick, self-inflating foam with StrataCore construction delivers an outstanding warmth-to-weight ratio. With an R-value of 4.4, the mat is suitable for year-round camping. The soft stretch knit fabric and extra thick foam provide exceptional comfort, while the clever design allows for a small pack size, ideal for backpackers. The WingLock valve ensures three times faster inflation compared to previous valves. Precisely moulded cap and intuitive handling ensure that the valve is as easy to use as a water bottle cap. To let the air out of the mat, simply open the valve and turn the wings. The air escapes twice as quickly as with the previous valve. A compact pack sack is included in the scope of delivery.
