Details Osprey Rook 65 Trekking Rucksack - Men's The Osprey Rook 65 backpacking pack has a simple progressive design with a highly adjustable ventilated backsystem with AirSpeed suspended mesh over a large airflow cavity. This allows the body to sink into the hipbelt and lumbar area of the pack, improving overall comfort and providing a very stable and supportive load-carrying experience. The torso length is easily adjusted using an innovative ladder-lock system. Rook 65 can be easily adjusted to ensure a perfect fit. To accommodate a wider range of torso lengths, these packs include dual load-lifter points on the upper frame, ensuring that the harness is comfortable in any position. A large, highly padded hipbelt ensures a comfortable fit and aids in carrying heavier loads in the pack. The Osprey Rook 65 has all of the essentials for multi-day backpacking trips, including a large capacity with upper lid and lower sleeping-bag compartment access points. An internal divider creates a separate lower compartment that can be unfastened when not in use. Multiple compression straps keep the pack stable without interfering with the mesh water bottle pockets. Smaller equipment can be easily accessed through dual hipbelt pockets and a large top-lid pocket with a key clip. The Rook 65 is compatible with Osprey's Daylite daypacks, allowing you to attach the smaller pack onto the bigger pack, increasing capacity and providing an option for when you leave your big bag behind for day excursions.
