Protects your backpack - but only 2-3 times.

The backpack protection consists in principle of a fiber fabric made of plastic with a sewn-in cord at the opening.
He is big enough even for trekking backpacks (70 liters no problem) and protects against dirt and abrasion during transport.
Also very important when traveling with the backpack: hides the many loops, cords and elastics and prevents snagging eg when transporting the plane.

From me, there are only 4 stars because:

- Looks taken the product after two flights quite and not more than 3 flights participates (admittedly, a certain Spanish airline famous not for her soulful luggage transport ...).

- The cord for tying is so smooth and slippery that you have to do about 48 knots until you can check in the bundle with a clear conscience. Something Panzertape is helpful ...

Highly recommended for this award yet!
