First of all the pictures of this pack do not do it justice! It is far more spectacular and stylish than the pictures show. I received it only a few days after paying online and was very surprised. I'm still finding new pockets and hidden features on this thing...its awesome. It's light weight, perfect for running, and for its size it is able to hold far more than expected. I can easily hold all I need when running to work and back. It has two large pockets, many smaller ones, two designed for water bottles, a rain cover and many creative little features that allow you to hid all dangling adjusting straps. This pack would be perfect for anyone who is looking for comfort, style, and convenience. Oh yeah, and a lifetime warranty!
