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 Women's ProLite offers adventurers the lightest and most compact self-inflating option on the market. The 1-inch (2.5 cm) pad boasts a 2.7 R-value, offering added warmth and a shorter length as an option for women or cold sleepers. The lightweight self-inflating pad features the high-performance WingLock valve, which has three-times the airflow rate of the classic valve thanks to a larger opening and one-way inflation. Like all Therm-a-Rest pads, the Women's ProLite is made in market to ensure quality and minimize environmental impact. The pad includes a compact stuff sack.
