Built for high-output days above tree line, the Patagonia Men's Terravia Alpine Short Pant delivers lightweight protection, all-day mobility, and rock-ready durability. The soft-shell fabric blends recycled polyester with spandex for breathable, four-way stretch comfort, while reinforced panels at the seat and front legs stand up to abrasion on granite, scree, and sharp limestone. A PFAS-free DWR finish sheds light moisture and wind, and the articulated pattern keeps you moving naturally on long approaches, ridge scrambles, and multi-pitch climbs.
