For lightweight self-inflating support, the ProLite Apex brings packable performance and legendary Therm-a-Rest support. The self-inflating foam measures 2 inches (5 cm) and features our StrataCore construction, a design that provides the best warmth-to-weight ratio of any self-inflating foam construction. The ProLite Apex 3.8 R-value allows adventurers to stave off the cold during three-season pursuits. The packable 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 ProLite Apex is made in market to ensure quality and minimize environmental impact. The pad includes a compact stuff sack.
