The Arbor Pack carries everything you need to get good and lost, especially when you aren't sure you're looking to be found. This backpack's main compartment closes with a large flap pocket and holds your inventory of everyday goods, from books, lunch and a shell to climbing shoes and chalk bag. A zippered pocket beneath the lid stashes a wallet and phone. Inside, a raised, padded laptop sleeve protects your computer from jarring knocks; it fits most 15" laptops, secures with a buckle closure and doubles as an insulated hydration reservoir when you hit the trails. Human Curve shoulder straps conform ergonomically to your shoulders and upper chest for all-day comfort under loads. Accessory patches and a fixed webbing loop carry ice tools, crampons or a yoga pad. Body is made from durable 600-denier recycled polyester with a polyurethane coating and a DWR (durable water repellent) finish.
