The Patagonia 22L Terravia Pack is built for all-day comfort and trail readiness with breathable, lightweight airmesh on the raised back panel and underside of the shoulder straps to keep you cool. A hip belt helps distribute the pack weight evenly and includes side pockets for convenient storage of small essentials. The pack features a small top zippered pocket with a key clip and a larger front zippered pocket for quick access to snacks or trail maps. An internal hydration reservoir sleeve with a pass-through between the shoulder straps allows the tube to be routed over either shoulder, while dual side pockets fit full-sized water bottles. Dual trekking-pole loops offer easy access during tough terrain and secure storage when not in use, and an exterior bungee lattice provides space for carrying an extra layer or additional gear.
