The Adrenaline Day Pack 20L Plus is streamlined for purpose and comfort, incorporating strategic design and waterproof materials to keep day hike essentials secure and dry.
Storing valuables is a cinch with the padded top zip, and two water bottle pockets keep hydration close by. The ergonomic shoulder straps and back panel ensure all-day comfort, while dual daisy chains boost carrying capacity and offer easy access for quick grab items. A nylon shell with polyurethane coating makes this water-resistant pack a protective bubble against moisture and rain.
Built for quick-strike alpine missions or casual day hikes, the Adrenaline Day Pack 20L is built to move fast and light.
