Looking for a first pad or a step up in comfort from closed cell foam? Look no further than the 1-inch (2.5 cm) thick, self-inflating Trail Scout. Its 3.1 R-Value will give users three-season warmth, while the premium foam core wrapped in woven-fabric is the same fundamental construction of some of our most durable and high-performance designs. Fitted with our one-way WingLock™ Valve [tech pop] to minimize inflation and deflations time so more time is spent enjoying the great outdoors. This pad is compact enough for forays into the backcountry and thick enough for next-level comfort for those car-camping weekends. Like all Therm-a-Rest pads, the Trail Scout is made in market to minimize the environmental impact of the manufacturing cycle and to ensure the Therm-a-Rest standard of quality that has been the foundation for thousands of rejuvenating nights under the stars. Comes with a compact stuff sack.
From 2020, there is a new industry standard for measuring the R-value (level of insulation) of sleeping mats – ASTM F3340-18. This new standard is the sleeping mat equivalent to the EN rating for sleeping bags.
You can now directly compare the R-value of mats rated using the ASTM F3340-18 with confidence that is a fair and accurate comparison between mats. In simple terms, the higher the R-value, the warmer the mat.
In general terms, an R-value below 2.0 is for summer use, 2.0 to 4.0 is for cooler 3 season use and 4.0+ is for winter temperatures. This will be also be dependent on your sleeping bag, how cold you sleep etc. Please contact our customer service team if you need advice on choosing the right mat for your activity.
