For unprecedented comfort when you go on an adventure in nature, the Trail Pro provides the legendary warmth and support of Therm-a-Rest mattresses in all seasons. The 3" thick self-inflating foam uses our StrataCore technology, a design that provides the best warmth-to-weight ratio of any self-inflating foam structure. With an R-value of 4.4, the Trail Pro allows adventurers to camp and hike all year round. The versatile self-inflating mattress features our high-performance WingLock valve that allows the mattress to inflate three times faster thanks to a larger opening and one-way inflation. Like all Therm-a-Rest mattresses, the Trail Pro is manufactured locally to ensure quality and minimize environmental impact. The mattress comes with a compact storage bag.
