Zen design meets catch-all versatility in the Refugio, our most popular backpack. With three main pockets, it keeps you organized without feeling fussy. The main compartment holds much of the load and comes with a dedicated computer sleeve that accommodates most 15" laptops (the same sleeve also accepts a hydration reservoir when your feet leave the cement). The second, zippered pocket holds smaller items like a paperback or tablet, pens, business cards or keys. A pocket on top of the pack protects sunglasses or an audio device. Stretch-woven side pockets accommodate a full range of water bottle shapes and sizes. Air Flow mesh on the shoulder straps and back panel prevents overheating while compression straps stabilize contents. Made from 450-denier 100% recycled polyester, with a 450-denier 100% recycled polyester base. The lining is 200-denier 100% polyester. All fabrics have a DWR (durable water repellent) finish.
