For long alpine rock routes and all-day movement above the tree line, we get started by putting on the lightweight, softshell Patagonia Altvia Alpine Pants. The recycled stretch fabric and articulated pattern ensure we have a full range of motion on the wall and trail alike while also standing up to abrasion from rock faces. Plus, a water-resistant finish helps shed light precipitation, while the adjustable integrated belt provides us with a secure, snug fit.
