The cool new Fanbrella protects you from the sun, heat and humidity as well as it does from the rain. This innovative summer umbrella uses a collapsible built-in motorized fan that produces a refreshing downdraft with an airflow of 654 feet-per-minute and has a 60″ diameter polyester canopy with PVC backing that blocks 99% of harmful UVA and UVB rays for a UPF of 50+, the highest attainable. It would be a cool solution at the golf course or beach, but for some reason it uses batteries to power it forup to 6 hours instead of uising solar power.
