Osprey ZEALOT 15 Hydrate Pack

Best hydration pack I've ever used for Mountain Biking, Hard Enduro Rides, Hiking, Skiing, Hunting, Amusement parks with the kids, etc. Use this pack for its intended design and purpose and you'll be very happy; it was not designed for, or intended to be used as a laptop, camera bag, etc; its a hydration pack designed for outdoor extreme fun. Comfortable all day wear, does not shift around when aggressive on the trails. The 3L reservoir is easy to refill, the bite valve works flawlessly, and out in SW you will need all 3L during the summer months / long rides (or all day hikes through Disneyland :) )

I got this bag to replace my older Osprey Manta which was a great bag .I wanted a little more room and the ease of one main pocket with exterior mesh pockets.The mesh side pockets are durable however don't be like me and let people your riding with just stuff their things they can't carry in it. If you stuff something in there that has hard corners or edges it may snag the mesh fabric if so it is going to rip. The bag is great since I am the person that carries everything for everyone else, tools and other repair items included. The tool pouch at the bottom is great, I do miss the Manta's rain cover. However the extra space and the harness system more than make up for it. Plus a better hydration pouch quick disconnect and that the whole top is a kinda a rolltop closure it makes cleaning really easy.
