The Bertha Double Patio Umbrella is ideal for backyard, garden, or poolside setups that require maximum coverage. This behemoth is our shadiest umbrella, with a canopy spanning 15 feet. Reinforced with a solid steel frame, it has five arms on each umbrella and two steel center arms that strengthen the large canopy.

Finally, the UV-resistant canopy is vented, allowing air to circulate and providing wind resistance. So chill out under the Berta Double Patio Umbrella, but dont expect a tan.
