I use this pack for everthing bike. Comuting, short rides long rides backcountry, and racing. It has never failed. It holds a full out fit for buisness casuale dress codes plus lunch. On race day or long rides with crazy descents it can cary everything needed. For The tool kit is secure, holds everything wanted or needed and sits low so not to affect balance much at all. It can hold 3 liters so the epic summer rides (like my attempt to ride up the Pikes Peak Barr trail) are feasable. Along with the many small stretchy pockets for snacks. All that is cool but common on mtb packs. What REALLY stamds out for me is that I can carry my rigid leg and arm armor plus a full face helmet on my back (wich allows for full speeds after all the climbing and way more comfortable climbs). I hit the ground at 20+ mph broken wrist but pack was fine. Another truly impressive feature of all Osprey packs is the almighty guaranty wich covered every piece of damage from my dog ate it to stupid clipping to plain worn out (all true stories but it didn't matter). I am a hard rider and my equipment feels it. I dabble in enduro racing and love to just ride hard and often and I need gear that keeps up, this pack makes the cut. After 1 year of ownership I can say for sure. This zealot will not give up his Zealot for anything!

This pack is great in my profession. I am an Archaeologist and I work in what is called Cultural Resource Management, we conduct archaeological surveys prior to construction of anything that may impact the environment and any documented or undocumented archaeological sites. My job requires a lot of back country hiking that this pack allows me to succeed at. The size is perfect for hiking through tight vegetation, the weight is light and the build is comfortable. So comfortable I forget it is on! And the ease of access allows me to retrieve my equipment with speed, and it is easy to manage as I am definitely a minimalist when it comes to such. Well done and thanks Osprey!

I used to have a camelbak for biking, but found it was too small. The Zealot has an opening on the back that can be used for a Full-Face Helmet or other things, side pockets, a stash pouch on the top for valuables, and a tool pouch on the bottom that is super convenient (comes with tool roll) the pocket for the reservoir goes the whole length of the bag so that when you open it, the whole back of the bag folds down. You can fit a bladder, jacket/layers, first aid kit and lunch in this pocket as well. There are also hip pouches that are good for a multi tool or leatherman, and two chest pockets on the straps that don't fit much. As always, you have amazing Osprey fit and finish, and it seems that the fabric is durable enough to take a spill on (though I have not tested that yet).
