Now you can turn your favorite backpack into a mobile hydration system. CamelBak has the Unbottle to attach a 70 or 100 oz. fluid reservoir to almost any pack you can think of. Easy to fill and clean, Omega Hydrotanium Reservoirs have a large opening to insert ice and fill quickly while allowing easy access to wash after use. Four clips allow riders to add this pack outside of any gear that may have provisions for straps. Add versatility to your non-hydration pack with a CamelBak Unbottle.
