Features Synthetic 14.7 oz 1,200-denier polyester with a TPU film laminate and DWR finish 49330-042 Description The Patagonia Black Hole Pack combines the fortitude of a climber's haulbag with the everyday features necessary for the school and office commute. This unisex backpack features waterproof fabric and a water-resistant construction and zippers to protect your gear from the rain, rough handling, and miles of abuse. The large main pocket has a computer sleeve (that holds most 17-inch laptops or a hydration reservoir), two mesh pockets, an organizer for a phone and zip drives, and a key keeper to ensure that your gym key stays put. This Patagonia bag also has padded shoulder straps for carrying comfort. A lid pocket for the small stuff seals with a moisture-shedding, reverse-coil zipper. It also has daisy chain lash points to secure a skateboard or yoga mat. A zippered front pocket holds quick-access items like your wallet, a boarding pass, and an electronic tablet. Carry everything you need with the Patagonia Black Hole Pack.
