The Patagonia Refugio Pack has one main compartment that holds much of the load and comes with a raised, padded sleeve, buckle closure, and accommodates most 15 inch laptops. The sleeve, equipped with a tube port, accepts a hydration reservoir. Pens, business cards, keys and other small necessities go inside the second pocket. An exterior, vertical zip pocket provides quick access to a wallet, plane tickets and a phone. The brushed tricot lined pocket protects sunglasses or an audio device. The stretch woven side pockets accommodate a full range of water bottle shapes and sizes. Air Flow mesh on the shoulder straps and back panel prevent overheating.
