A classic pad in our MAX size for extra sleep surface, the updated Trail Pro gets a refreshed look and more sustainable fabric while providing exceptional comfort, year-round warmth and legendary Therm-a-Rest support. The self-inflating foam measures 3 inches (7.6 cm) and features our StrataCore construction, a design that provides the best warmth-to-weight ratio of any self-inflating foam construction. The 4.4 R-value lets you comfortably enjoy year-round backpacking and camping. It also features a high-performance WingLock valve, which has three-times the airflow rate of a classic valve thanks to a larger opening and one-way inflation. Like all Therm-a-Rest pads, the Trail Pro is made in market to ensure quality and minimize environmental impact.
