Beach umbrellas are made of different fabrics. Commonly, these include canvas, cotton, and polyester. Canvas is heavy-duty and waterproof. Cotton repels heat naturally and is relatively more affordable than most materials. Lastly, polyester is durable, low-maintenance, mold-resistant, wind-resistant, and wrinkle-resistant. Polyester is highly preferred when it comes to beach umbrellas because it blocks the sun effectively and dries quickly. A good example of a beach umbrella made with polyester fabric is AMMSUN Heavy Duty Beach Umbrella. Check it out in this guide we have prepared for you.
