Markus and Daniel Freitag have been providing the world with waterproof, sturdy and unique bags for travel and work since 1993. As well as practical design and professional construction, Freitag bags have another common trait – they are Earth-friendly, being made from recycled transport truck tarpaulins.

Their latest creation is called the Zippelin and is the world’s first inflatable rolling travel bag. With a capacity of 85 liters, the Zippelin is quite roomy and even includes a zippered pocket outside for passports or documents. The frame has been removed to decrease weight and in its place is a zippered pocket around the inside which holds a bicycle inner tube that, once inflated with a standard tire pump, provides ample support. The two wheels are detachable and can store in the front pocket when not in use. If you don’t want to roll it on the wheels, it can be carried on your back via the thick carry strap. Even better, when deflated, the Zippelin Bag folds down to the size of a two-liter bottle for storage.

Freitag hand-cuts the panels for best artistic effect from the recycled tarpaulins so each bag is one-of-a-kind, letting you easily pick it out on the baggage carousel.
