Banjo Brothers 01064 medium frame pack is designed to maximize the gear-carrying efficiency of your bike. Built from tough-as-nails ballistic nylon with waterproof zippers and a “no-rattle” zipper-pull garage, you’ll quickly wonder what you did without this bag. Two pockets – one full size and one flat pocket to organize smaller items – includes wallet pouch and key clip. Banjo Brothers medium frame pack fits up to a 70 ounce hydration bladder. Cut-to-length straps fit oversized tubes to 3 inches in diameter. Small fits sloping frames down to 15 inches. Dimensions are 15.5 by 5.75 by 2 inches.
