The Tuuci Manta umbrella was inspired by the graceful ocean flight of the manta ray. Looking down on the shade structure, the shape is square. But the undulating ribs change the umbrella into a functional sculpture. Tuuci makes top-quality umbrellas. Drawing from a decade in the marine industry, their marine anodized aluminum alloy structure with stainless steel and thermo-polymer components really stand up to salty, wet environments and harsh sun. The sunbrella canopy is a heavy awning-grade fabric that resists fading. Available in the sharkskin silver canopy (shown) or any Sunbrella awning-grade fabric. The sharkskin reflective fabric offers 98% UV protection and is water repellent. The pockets are reinforced with ballistic nylon for extra durability. Tuuci's components are 100% repairable or replaceable and come with a five-year limited warranty on the canopy, canopy ribs and struts, and connecting brackets. A 15 year warranty includes the center pole, top and bottom hub and stainless steel hardware. As with any umbrella, we recommend keeping it closed when not in use, as damage from weather or misuse is not covered under warranty. Made in USA. Measures 8.5' square. This item is available for shipment within the Continental US only at this time.
