The Osprey Rook 65 Backpack is built to make backpacking as easy as possible. An integrated rain cover protects the main compartment topped by a fixed-top lid with external zip pocket. An internal reservoir sleeve for hydration (bladder not included) and a zip sleeping-bag compartment with floating divider fill out the body of the rugged pack. Built for convenient backpacking, the Rook offers 2 side stretch-mesh pockets and 2 hip-belt zip pockets to round out the available compartments. The ventilated pack panel adjusts to fit your torso, and it spreads weight evenly to the 4mm peripheral LightWire frame. This Osprey backpack also has an adjustable sternum strap with integrated rescue whistle. 600-denier polyester. Imported.
