Banjo Brothers has done me the ultimate solid with the production of this semi-custom branded version of their popular waterproof backpack. It’s the same design and features the fully-waterproof replaceable liner as the other Banjo backpacks, but the shell is a classic heavy-duty 20oz cotton canvas with a water-repellent dry-wax finish. Tested and abused by some of the toughest characters in the business. 1500 cu in. ** Newest accessory pouch version fits phones (or phone inside a case) up to 5.25″ x 2.75″ x 0.75.
