The ProLite Plus women's sleeping pad offers support and comfort in a self-inflating mat, while the diagonally die-cut foam saves weight and has a small pack size. The 3.8 cm high mat has an R-value of 3.9 with high thermal performance at a shorter length compared to the ProLite Plus.The versatile, self-inflating mat has a high-quality WingLock valve that allows the mat to inflate three times faster thanks to the larger opening and inflation in only one direction. Like all Therm-a-Rest mats, the Women's ProLite Plus is made domestically for quality and environmental protection. Included in the package is a compact stuff sack.
