Fox Low Pro Hydration Pack

One of the best version's of the minimalist, low-volume hydration packs ever is the Fox Low Pro Hydration Pack. It's got a usable amount of storage between it's zippered pocket and a quick-access stash pocket perfect for gel packs or an energy bar. Plus the storage bungee runs nearly the full-length of the pack, providing room for one or two layers worth of clothing.

Hydration duties are handled by the 2 liter (70 ounce) Hydrapak reservoir, which is accessed by a full-length side zipper for easy fill-up. The reservoir itself has such user-friendly features as a detachable delivery hose, a fold-over, slide-top opening, and an integrated hanger in the packs reservoir storage compartment.
