This deluxe red bottle backpack measures 19″ x 13″ x 8″ and is constructed from tough 600D polyester fiber. It sports ergonomically curved and padded shoulder straps for day-long comfort. One main zippered compartment complements an additional five front and side zippered pockets, one of which is mesh to allow you to easily locate regularly required items. A reflective safety strip adds visibility to the bag at night and the two mesh side-pockets allow for good spots for additional water bottles for the long ride home.
