Durable nylon with subtle stretch, quick recovery, and a water-resistant finish makes these shorts a mountain summer staple.

A solid, high-capacity short is the uniform of mountain summers and our Coburn XT is made tough and technical enough to withstand any activity the season sends its way. Tetonic Twill™ is the foundation—a durable nylon material with subtle stretch, quick recovery and a water-resistant finish. Drop-in hand and flat, zippered cargo pockets provide maximum storage capacity, while hidden-zip back pockets stow critical items. Subtle elastic waistband keeps them riding at the right height whether seeking out river, trail or road trip.
