I love this hydration pack. It goes with me mountain biking, fast day hiking, quick trips on my favorite trail, and even on road trips to keep my h20 cold. It does not bounce around too much when hiking or getting aggressive with my pedals. It has just enough room for some lunch, basic gear you would want or need for quick trips, and a few bike tools. The only thing I would have liked to see on this pack is the AirSpeed back panel found on the Atmos/Aura packs to help with ventilation.
Awesome Pack. Another high quality and thoughtfully designed product from Osprey. I use mine for mountain biking and after a year I have nothing but good things to say. The hydration bladder is really easy to fill and slides in and out of the pack with no problem. The removable tool pouch in the bottom section is a nice touch. It keeps everything organized and in its own place. The pack has plenty of adjustments so I can make it fit perfect regardless of what I am wearing. The “10” size was perfect for me. It has just enough room for my riding essentials (tools, spare tube, mini pump) as well as personal items like keys, cell, snacks, and maybe even a small jacket. The helmet holder is great for keeping my gear organized to and from the trails. This is a sweet pack and you should definitely get one.
