Bring a legendary amount of comfort into the backcountry with the ultra-comfy Therm-a-Rest Trail Pro. Equipped with the WingLock Valve which is able to inflate a pad three times faster than a standard valve thanks to a larger barrel and optional one-way inflation. Inflates to an impressive 3 inches making it one of the thickest self-inflating backpacking pads available, features Thermarest's StrataCore construction that helps save weight while adding warmth, uses an ultra-cozy stretch knit fabric to maximize comfort in the backcountry, and boasts a 4.4 R-value for year-round adventuring (R-value measures the material's ability to insulate; the higher the R-value, the warmer the sleeping pad). Made in the USA.
