Modular gear straps make this pack highly versatile and can be adapted to attach gear to the outside of the pack. This backpack is made using body fabric and has extra stow space in two large detachable hip fin pockets. And there’s a zip-out bottle holster for a water bottle. The back length adjustment, snug-fitting hip fins and pivoting shoulder straps create a tailored fit no matter what the capacity, and mesh further enhances the comfort.
