Rolling or non-rolling, hardshell or soft-sided, compact or capacious; there are only so many ways you can build a suitcase, right? Freitag begs to differ. The Zurich-based apparel and accessories brand claims to have created the world’s first one-of-a-kind luggage that expands to accommodate several weeks’ worth of clothing yet flattens into a tight roll for storage. Think of it as your own personal air ship.

Dubbed the “Zippelin,” the luggage is designed for long-haul, intercontinental travel. Clad in recycled truck tarpaulin and featuring a pair of skateboard ball-bearing wheels to scoot around on, the Zippelin boasts 85 liters worth of space at full sail. Deflated and coiled into itself, it takes up no more space than the “two liters of booze you bought at duty-free,” Freitag said.

The trick lies with a hidden garden-variety bicycle inner tube, which you can inflate with a standard pump. Accidental blowout? A zippered pocket makes easy work of replacing the tire.

Freitag is currently accepting preorders for the Zippelin on Kickstarter, where it has already doubled its original funding goal of $120,000.

Although the company expects to retail the Zippelin at €520—that’s $618 in American dollars—early-bird pledgers will be able to snag 100 of the bags for €380 ($451) for delivery next April. Another 300 pieces will be available for €420 ($499) for a May 2018 delivery.

The campaign runs from now through October 12.
