The Osprey Viper 13 is the largest of the Viper Series with 800 cubic inches of storage capacity, a decent amount for sure.

The large hose and decent bite valve on the included bladder both work great and the reservoir didn’t leak on me. The bladder, which I can’t rave about enough, works, fits, and cleans well. The molded form ensures that even if filled to the brim with water, you don’t feel like there’s a salami on your back.
