And thanks to the external zip pocket, there's plenty of space for your keys and other valuables in the pack.

About CamelBak
CamelBak is the originator and world leader in hands-free hydration systems. The first CamelBak products proved to be very popular among mountain bikers and motocross riders, because it allowed them to drink without taking their hands off of the handlebars in technical terrain. The product began to cross over into other sports when scientific studies showed athletes drank more fluids and performed better when they wore a CamelBak. Since then, athletes from an ever-growing list of sports and activities use CamelBak hydration systems for their convenience and performance benefits.

In addition to cycling, CamelBak has Hands-Free Hydration systems for hiking, running, snowboarding and skiing. CamelBak’s state-of-the-art packs and hydration systems have benefited athletes, outdoorsmen, and soldiers around the world. While CamelBak has grown tremendously since the early days, one thing hasn't changed: CamelBak still believes in the performance advantage that proper hydration delivers for just about any activity. The privately-held company is headquartered in Petaluma, California.

Rating : - Excellent mid to long range hydration
I purchased this with the intent of doing 10 milers and half marathons in summertime Iraq, and its capacity is perfect. My aim was to have something to sip, to avoid that dry mouthed feeling, without much weight or inconvenience.

There is minimal bouncing, if the straps are adjusted well, and I hook the tube into the webbing on the opposite strap to keep it from bobbing around. The lack of a smoother way to take care of the tube is the only reason I can't give it five stars.

It rides very comfortably; I haven't had any issues with chafing, and often forget I'm wearing it (after the first 3-4 miles, once things settle down).

I wouldn't bother with a pack for shorter runs, but this won't be big enough for longer ones if you're a guzzler. I still want a full bottle of water when I finish running. Also on size, the zippered pocket is outstanding for carrying a couple of ID/credit cards and a key, plus perhaps some chapstick or other small item, but nothing much larger.

I had some sloshing issues that were taken care of when I realized extra air needed to be squeezed/sucked out before running.

In short: love it!
