The Patagonia Terravia Alpine Pant uses an articulated pattern and four-way stretch fabric built for the kind of all-day movement a long alpine rock route demands, from the approach to the climb itself. A low-profile waistband with a removable, adjustable belt and lie-flat pocket construction keeps everything comfortable under a harness, while a right-thigh pocket sits above the knee and below the leg loops so it never gets in the way. Reinforced panels at the seat and front legs add abrasion durability exactly where rock wears a pant out fastest. What Our Gearhead(R) Experts Are Saying:"I high-stepped onto a foothold with a harness and a full rack on, and never felt the waistband bind or the thigh pocket catch a leg loop."
