From running to catch a flight to traversing the streets, rolling travel bags need to be able to withstand all of the bumps and scuffs that come along with traveling. ZÜCA travel bags are constructed with a light, super-strong aluminum alloy frame, making them ideal for navigating airports, cities, and more. The insert bag is made from premium 600D polyester and coated with water-resistant polyurethane, ensuring that the contents within are safely protected from the elements. The oversized polyurethane wheels make it easy to navigate hallways, stairways, and sidewalks.
