As the original inventor of the self-inflating sleeping pad, we’ve mastered the art of crafting these high-performance pads for camping and backpacking. The ProLite is the foundation of our ProLite line, offering adventurers the lightest and most compact self-inflating option on the market. The 1-inch (2.5 cm) sleeping pad uses diagonally-cut foam to increase warmth while saving weight, giving the pad a 2.4 R-value for three-season adventures. The lightweight self-inflating pad features the high-performance WingLock valve, allowing the pad to inflate three times faster thanks to a larger opening and one-way inflation. Like all Therm-a-Rest pads, the ProLite is made in market to ensure quality and minimize environmental impact. The pad includes a compact stuff sack.
