Patagonia's ambassadors' request: a super-clean climbing backpack stripped of everything but the features that matter most when you're pushing the limits on big alpine ascents. For moving fast in Alaska or the Karakoram, this function-driven pack carries the loads of a multiday kit without interfering with your ability to move efficiently. It features an integrated, asymmetrical spindrift collar that opens wide and closes in a single motion for fast packing. A secondary collar protects your gear from ugly weather, allows serious overstuffing and holds gear securely when the pack is hanging at belays. The removable frame sheet, made from a lightweight aluminum rod and covered with mesh, provides support for weighted loads and moves with you as you bend and flex. Ergonomic shoulder straps (with load lifters) match your torso's contours for 24-hour comfort, and the padded hip belt is removable when you prefer a simple webbing belt. Four rows of exterior daisy chains provide lashing options for a rope, helmet and pad; ice tools attach via an integrated buckle and tool pocket. Other details include compression straps to carry skis and cinch down loads, an asymmetric profile for elbow clearance and a zippered pocket on the lid for quick access to small essentials. Made from lightweight yet durable 6.25-oz 210-denier nylon double-ripstop and 6.05-oz 400-denier nylon ripstop treated with a polyurethane coating and a DWR finish, and lined with a 1.8-oz 40-denier nylon double-ripstop with a polyurethane coating and silicone finish.
