The Flight Bag 50-65L protects your backpack from wear and tear when travelling by air and also serves as a rain cover when you arrive and go trekking. It has generous handles on the top and on the side, a zip with loops for a padlock, and a drawcord for adjustment. The extra cord can be rolled into a special opening for storage during transport. A transparent pocket provides space for an address label. It can be stowed in its own pocket when not in use.
