This protective cover is treated to be fade and water resistant; which prevents moisture from getting through to your umbrella and fading to the umbrella fabric. The highly breathable nature of the polyester material also keeps your umbrella free of mold and mildew. A 360 degree auth-locking draw cord system allows you to cinch the cover tightly. There is also a heavy-duty, rust-free nylon zipper and runs the length of the umbrella cover; which makes it easy to put on and take off.
