It would be cool to have a hover-pack that would just follow, a few inches away from your back, while you hike. The NVIS back panel on the CamelBak Womens Adventura Hydration Pack doesnt quite make this a hover-pack.
Your belly doesnt make you ferocious. But the CamelBack BlowFish Hydration Pack 3L does endow you with the really cool capacity to make your pack much larger with one simple swipe of a zipper.
Take a swig of water out of your CamelBak Womens Charm Hydration Pack to calm your thirst when you hike down Angels Landing in Zion or mountain bike in Moab.
