The Osprey Packs Rook 65L Backpack prioritizes our comfort, so we barely even notice the miles adding up beneath our feet. The AirSpeed suspension system keeps the bag sitting just off of our back, allowing refreshingly cool air to flow across our back while also encouraging weight to be carried by our hips for more stable weight distribution. The adjustable torso length ensures a perfect fit, and dual load-lifter points on the upper frame keep the harness comfortably in position. The pack is trail-ready, featuring a sleeping bag compartment and multiple external pockets to keep us organized on the trail.
