Our 55-litre Alpha AR is your pack for epic multi-day climbs. Made to withstand rock, ice, and alpine environments, it’s built from our Hadron™ LCP (liquid crystal polymer) grid fabric - a proprietary material redefining the standard for lightweight abrasion resistance and durability. A removable framesheet and lid let you shed weight, and the main compartment is accessible via WaterTight™ side zip or pull-to-open/pull-to-close top. Custom daisy chains and dual dog bones securely attach tools and gear, the ergonomic hipbelt and harness provide a comfortable carry, and rope straps under the lid.
