The Sun Defender Complete is the largest floating umbrella on the market and yes it does work even in the wind. The Aqua Shade Base is the heart of our company; it allows you to use your own existing umbrella to save money or purchase your own umbrella and get the perfect fit of size, material quality, and color. Plus, the Aqua Shade Base can be transformed into an Ice Chest to create your own floating oasis. We invite you to compare with any floating shade out there; once you do you will see there really is no comparison.
