Freitag has been crafting bags and backpacks for decades using recycled tarps. But the Zippelin is completely new. It’s an 85-liter rolling travel bag that inflates. When not in use, it rolls up & stores in a compact 8-pound bundle. When you’re ready to travel, pump it up with a standard bike pump & roll. It’s got multiple exterior pockets, removable wheels, shoulder carry straps, and carry grips all over. The recycled tarp material means no two bags are alike. A funded Kickstarter.
