Product Features: The CANOPY is manufactured from a clear POE material offering a very waterproof covering. We always ensure that the canopy is broad enough for the job and this umbrella is no exception having a deep DOME shape and a canopy with a diameter of 82cm enough to keep you very dry indeed. This umbrella is AUTOMATIC meaning that at a touch of the button the canopy smoothly and firmly opens without trouble time and time again. The SPOKES we specify are FIBREGLASS which offer superb flexibility and strength in strong weather ensuring that they FLEX and don't break or snap as many inferior umbrellas do which have thin metal weak spokes.
