The Pro Lite Apex Self-Inflating Mat is compact and offers excellent support with its 2-inch thick construction. Its thickness and StrataCore construction provide the best warmth-to-weight ratio of any self-inflating mat. The 3.8 R-value keeps you cool when sleeping outdoors in spring, summer, and fall. The convenient and efficient WingLock one-way valve allows you to inflate the mat three times faster because the air won't escape when you stop to breathe. Like all Therm-a-Rest mats, the Prolite Apex is built to maximize quality and minimize environmental impact. It comes with a compact storage bag.
