The Osprey Talon 22 is a solid lightweight do almost everything pack. It features a bunch of pockets for your organizational needs. There are two on the hip belt for storing small items like digital cameras or nutrition. There are two pockets on the shoulder straps as well. These are a bit smaller and can fit music players or cell phones. The pack has a large main compartment and a smaller essentials pocket also accessible from the top. Inside the main pocket there is also a small Velcro closing pocket that can be used to store important items; it is not very big (15 cm Tall x 14 cm Wide). The most useful pockets I have found are the stretchy pockets on the outside of the pack. There is one on each side which is good for water bottles or other small items you need to stash quickly. There is also a large stretch pocket on the outside of the pack which is great for a jacket. Osprey has really thought out the details on these outer pockets, the main back pocket has a drain hole built in to it. The side pockets have a mesh section at the bottom so they can also let out water.
