good pack
I use this pack mainly when I ride my mountain bike for a full day of riding. I like the fact that I can use my 3L osprey hydraform reservoir . Plus have room for food, light jacket, camera and the pockets inside are great for storing small stuff. When one uses the "OTF (On-The-Fly) Compression" it sucks the pack tight to my back and dose not flop around while I am riding my bike.

Great pack
I love this pack. There are a lot of pockets to keep things neat. I use the main compartment for clothes. The next compartment has smaller pockets great for small items (lighter, nail clippers, etc.) This compartment is great for lunch, headlamp etc. There is also a fleece lined pocket on the outside for glasses, GPS, etc. The only complaint I have is that the waist belt pockets are kind of useless. They are to small for a small camera and to far back. I wish they re-designed the waist belt. I used this pack climbing the Middle Teton in early Sept. It was about 20 degrees when I started out from the Meadows. As I climbed, the pack held my Arcteryx Atom jacket and my base layer (top and bottom).
