GrahmMatterhornwrote a review of Osprey Packs Zealot 10 Hydration Pack on February 25, 2013
This pack has a ton of pockets for storage and yet still keeps a low profile while your riding. The best thing about it is the tool pouch that clips on and off with in a zippered pocket and it is located on the bottom of the pack so it disperses the weight better. The sizing is true to the fit guide, but it is a large pack even compared to the Osprey Manta, the Zealot is more streamlined though. Once you get it on you dont even notice it and the venting is great. The reservoir is the only downfall because after many uses the screw cap starts to leak.
