OspreyOsprey Men's Rook 65 Dark Charcoal/Silver Lining

Rook has all the important functions for multi-day trips: the backpack is spacious and can be opened both at the top and via the bottom compartment for sleeping bags. The inner divider of the bottom compartment can be removed when not in use. Several compression straps stabilize the gasket and are independent of the mesh pockets for the water bottle. The backpack has two pockets in the hip belt and a large pocket in the top lid with a key holder for easily accessible storage of small items.

If you want, you can combine Rook with Osprey's Daylite backpacks by attaching the smaller backpack to the larger one. It provides extra capacity and the opportunity to leave the large backpack in the camp when you make shorter trips with the daypack.
