Featuring a streamlined, straightforward design, the Osprey Rook 65 boasts a feature set that includes a highly adjustable suspension, durable fabrics, and a breathable backpanel. And perhaps best of all, it offers these at a budget-friendly price. The pack uses a lightweight peripheral frame with a HDPE framesheet to provide flexible but strong support for your load. The adaptable suspension system allows a torso adjustability range of 4”, making this pack suitable for a wide range of users. The backpanel and harness use tensioned, padded, edge-free mesh with side ventilation to provide breathability, allowing you a cooler, dryer and more comfortable load-hauling experience. The adjustability of the harness, along with load lifters and an adjustable sternum strap, let you achieve the best fit. The sternum strap features a rescue whistle in case of emergencies. This pack has an internal volume of slightly under 4000 cubic inches, or 65 liters. Inside, an integrated pocket makes the pack compatible with up to a 3 liter reservoir (not included). The fixed top lid has a zippered pocket for quick-access items like sunglasses and maps. There are side mesh pockets for water bottles, and cord loop attachment points on the front and lid. The hip belt has two zippered pockets for keeping small items secure. There is a zippered sleeping bag compartment with a floating divider as well as 2 removable sleeping pad straps on the exterior of the pack. You can be confident that the pack will hold up to your adventures, as it's constructed with tough 600 denier fabric. The bottom is reinforced with durable 1000 denier fabric. Osprey also includes a removable integrated raincover so that you'll never find yourself without protection in bad weather. The Osprey Rook 65 is available in your choice of colors.
