Why We Like The Osprey Rook 50L Backpack

The Osprey Rook 50L Backpack features durable, eco-friendly fabrics for a pack that should last us years of backpacking. The lightwire frame helps transfer the bulk of our load to our hips while the Airspeed back panel features ventilating grooves to moderate annoying back sweat. The 50+ liter capacity can hold a few days of gear with convenient pockets to keep our small items organized. We also like the integrated rain cover—a nice value feature to keep the contents of our pack dry without us investing in dry bags and pack liners.
