Superlight, incredibly durable, comfortable - the Alpha SL 23 is a summit pack that doesn’t compromise. Sized for final pushes and minimalist approaches, it’s made from Arc'teryx's Hadron™ LCP (liquid crystal polymer) grid fabric - a proprietary material redefining the standard for lightweight durability. Access to the main compartment is fast and simple, and smaller pockets - one internal, one on the lid - hold small essentials. It packs easily into a larger pack, dual dogbones secure your tools, and an integrated system securely carries your rope.
