Designed for one to two day speedball ascents in places like Chamonix and Patagonia, this streamlined, yet highly versatile climbing backpack has everything you need, but absolutely nothing more. 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 hip belt has removable pads for simplicity. 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, a hydration reservoir pocket, an asymmetric profile for elbow clearance and a zippered pocket on the lid for quick access to small essentials.
