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 bluesign(R)-certified 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 VariSlide back length adjustment, snug-fitting VariFlex hip fins and pivoting ActiveFit shoulder straps create a tailored fit no matter what the capacity, and Air Spacer mesh further enhances the comfort.
