No matter what we throw at it, the Kestrel 68L Backpack can handle the terrain. Osprey's earth-friendly fabrics don't cut back on durability, so we can continue to hoof it for days or weeks through bush-covered alpine, sandy desert, and rocky cliffs. This pack's massive capacity has us covered on extended excursions, even including a rain cover to keep us prepared for unpredictable weather. The side compression straps let us adjust our load as needed, and they secure our equipment while we trek. The AirScape back panel provides a stable carrying system, keeping the pack close to our body while allowing airflow for active comfort.
