The Rumbrella® Travel Umbrella incorporates many of the best-in-class features. It's constructed with nine resin-reinforced fiberglass ribs that are designed to withstand even the harshest winds. However, its collapsible design also means it easily fits into a backpack or carry-on bag. It weighs in at just over a pound. The canopy fabric is covered with a layer of Teflon, so the umbrella dries quickly once you’re out of the rain. In addition to protecting against downpours, Rumbrella's signature fabric protects against UV rays.
