Scott R.wrote a review of Osprey Packs Raptor 14 Hydration Pack - 854cu in on September 3, 2014
Familiarity: I've used it several times
The straps are great, the comfort level is great, the pockets and buckles are great, and the big 1000z water bladder is great. This is just about the perfect pack for longer distance (over 2 hours) mountain bike trips. Helmet clip is a neat addition. I will use this for light day hiking trips as well as it holds a ton of stuff for the size. I can even toss my running shoes in if i want to do a brick workout and do some trail running after/during my ride. The only wonky thing is the magnet that attaches the mouth piece to your chest. It is difficult to put on when you are on a trial and better suited for using on an easier stretch of trail as it requires one hand off the handlebars to accomplish.
