Tatonka Protective bag Single transport bag

Why does a waterproof backpack actually need the Tatonka protective bag simply? Even if a backpack should best be transported on the back, this does not always work. Especially airports often do not allow trekking backpacks, because they can get caught in conveyors. The problem is solved if you simply put your backpack in this practical and, at 215 g, very light Tatonka transport sack. Close the drawstring with cord stop and you're ready to take off.
