SEASONS SELECT® outdoor patio market umbrella covers have been designed based on years of research to provide the most durable protection for the value. Our patio umbrella covers are constructed with a unique combination of premium 350 gram Vinyl and 300-Denier Polyester to provide a multi-layer defense throughout every season and variety of weather elements. Our high-density vinyl (HDV®) fabric combination increases water resistance, prolongs color fading, and provides a soft polyester interior to protect and shield expensive umbrellas and canopies from abrasions while reinforcing the covers overall reliability. SEASONS SELECT® outdoor patio market umbrella covers will protect your investment for many seasons. Finding the proper outdoor market umbrella cover is essential to the overall protection of your umbrella. The umbrella cover you choose will fit and perform better if it's slightly larger or wider (1-2 inches in total dimension) than the market umbrella when folded onto a pole no longer than 69” H and 10” W. Our patio market umbrella cover works for a variety of canopy shapes (round, square, or rectangle) that range from 6 to 10 ft. in dimension. The cover is not meant to extend full length of pole to umbrella base and is used to protect the canopy up to 69" when folded only.
