"Taking its inspiration from the classic rucksack, the Osprey Kestrel LT 45 Backpacking Pack keeps gear within easy reach. A durable water-repellent finish combines with an included rain cover to protect against the elements. The top-loading main compartment boasts plenty of room for an overnight hike, and it cinches and zips shut. 3 sliders on the front and side zippers grant access from any point. Plus, the top lid itself features 2 zippered pockets, a key clip, and lash points. An internal sleeve provides room for an optional hydration reservoir (not included), so you can stay fueled on your adventure. A shove-it pocket with stretch gussets, dual-access stretch side pockets, and zippered hipbelt pockets provide easy-access storage for must-have items. An AirScape back panel delivers cushioned, close-to-body comfort, while adjustable torso length offers a precise fit. Made of bluesign APPROVED 100% recycled nylon.
