Rich Wheelerwrote a review of Osprey Packs Raptor 14 Hydration Pack - 854cu in on November 23, 2016
Familiarity: I've used it several times
This is a great pack. Once again Osprey has thought of everything. From a really easy to access hydration bladder to super functional zipper handles. This may be only a 14 liter but It can easily fit as much as a standard 20 liter bag. There are plenty of nooks and crannies to stow everything you need for a day hike. The shoulder straps hug in close enough to allow free range of motion with your arms. I am a big fan.
