One umbrella is all you need! The 39"L Onebrella is a shield from the wind, sun, and rain at the beach, the golf course, or anywhere you want to go. An incredible 52" diameter with built-in parachute vents allows air to flow through the Onebrella, keeping wet weather out and withstanding hurricane force winds. Includes convenient carrying case and removable, foldaway extension pole for a longer handle.
