Thermarest's women’s ProLite Plus sleeping pad offers the stability and comfort of a self-inflating pad while diagonal-cuts create a lighter and more packable piece for the backcountry. The 1.5-inch (3.8 cm) pad boasts a 3.9 R-value for added warmth and a shorter length when compared to their standard ProLite Plus. The versatile 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 Plus is made in market to ensure quality and minimize environmental impact. The pad includes a compact stuff sack.
