Therm-a-Rest Prolite Apex Self-Inflating Sleeping Pad

The Therm-a-Rest Prolite Apex Ultralight Self-Inflating Backpacking Pad with WingLock Valve is the ultimate in lightweight and stable self-inflating comfort, offering unparalleled warmth without adding extra bulk or weight to your pack. With an R-value of 3.8, the ProLite Apex is designed for comfortable three-season backcountry adventures (R-value measures the material’s ability to insulate; the higher the R-value, the warmer the sleeping pad). This innovative pad provides the best warmth-to-weight ratio for self-inflating pads, thanks to its unique StrataCore construction, which consists of a continuous layer of thermal foam nestled between alternating ridges of air and foam. The 2-inch thick sleeping pad is made with thermal self-inflating foam; simply top it off with a few breaths after the foam expands. It is also equipped with a reliable and durable WingLock valve, which enables the pad to inflate three times faster than a classic valve and allows for lightning-fast deflation. The ProLite Apex comes with a stuff sack to protect the pad when it's packed down. It is available in three sizes: Regular (measures 72x20x2 inches inflated, packs to 11x5.2 inches, and weighs 22 ounces), Regular Wide (measures 72x25x2 inches inflated, packs to 11x5.5 inches, and weighs 28 ounces), and Large (measures 77x25x2 inflated, packs to 13x5.5 inches, and weighs 30 ounces). The pad also comes with a manufacturer’s limited lifetime warranty. The Apex ultralight sleeping pad offers an unparalleled balance of warmth to weight and is the ultimate in fast and light, self-inflating comfort. The patented Triangular Core Matrix delivers warmth with its continuous layer of thermal foam nestled between alternating ridges of air and foam. The Regular size measures 72x20x2 inches when inflated, packs to 11x6.8 inches, and weighs 22 ounces; a stuff sack is included, and it is made in the USA.
