The small size of the Osprey Airporter LZ was built for bag and backpack protection when travelling on airplanes, buses and trains. It’s made of rugged 210D nylon double diamond ripstop fabric and features a lockable zipper for easy-opening and enhanced security. A comfortable stow away shoulder strap, along with top and side grab handles offer different carrying options. Osprey constructed the Airporter LZ to stuff into its own top pocket for compact storage. This model of the Airporter LZ is designed to protect duffle bags and backpacks less than 50L in size.
