Patagonia Refugio 28 L Day Pack. Zen design meets catch-all versatility in the Refugio backpack. With three main pockets it keeps you organized without feeling fussy. The main compartment holds much of the load and comes with a raised, padded computer sleeve that closes with a buckle and accommodates most 15-inch laptops. This sleeve also accepts a hydration reservoir when your feet leave the cement. The second, zip-closing pocket holds smaller items like a paperback or tablet, pens, business cards, and keys. An exterior, vertical zip pocket provides quick access to a wallet, plane tickets and a phone; a brushed tricot-lined 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 prevent overheating. The sternum strap has an emergency whistle, and compression straps stabilize contents. Made from 420-denier 100% nylon oxford plain weave, with an 840-denier 100% ballistic nylon bottom. The lining is 200-denier 100% polyester. All fabrics have a DWR (durable water repellent) finish.
