Between wind, rain, and scorching sunlight, there are plenty of things that can degrade your shade umbrella’s quality and leave you without protection during the hottest months of the year. If you're looking for a market patio umbrella that can withstand the elements, you'll want one with fiberglass ribs and an aluminum pole. The fiberglass ribs are flexible, so they will not snap as easily on windy days. Meanwhile, the aluminum center pole is both lightweight and strong enough to provide the support to hold aloft the canopy and its eight ribs. When in use, the umbrella’s ribs can be eased open by turning the crank centered on the pole, and the collar tilt mechanism lets you tilt the canopy for angled shade. Plus, the beautiful fabric is composed of high-performance synthetic Olefin fibers that have been solution-dyed for longevity to be strong, durable, and resistant to stains, mildew, and fading. With the protective features this umbrella offers, you can relax with the knowledge that this umbrella will steadfastly shade you and your patio during the blistering heat of summer.
