pretty good day pack
Quality is very good. Pack is light and has detailed construction some other lightweight brands skip. This is my first Osprey pack. My other day pack is REI Flash 18. My backpack is 6 Moon Designs Traveler. Overall design works well for me. I put my jacket in the water reservoir area because I usually carry water in gatorade bottles for a day hike. This keeps me from wrestling with my jacket every time I want to grab a smaller item from the main compartment. Huge smartphone (Samsung Charge) fits in the hip pocket.
Only problem is the mesh side pockets are not deep enough to reliably hold a 20 oz gatorade. A 12oz gatorade fits better, but he elastic is not quite strong enough to hold reliably (if you bend forward, for example). The lower side compression straps are done nicely and allow flexible configuration. I use these to wrap around the top of the gatorade bottle (20oz and 12oz) to hold it in the side pocket. It's an extra step and takes a little practice to do with pack on. Wish the side pockets were deeper so I could just stick the bottle in with one step.
