BLUNT Classic Umbrella
BLUNT's Classic Umbrella is likely the best umbrella you'll ever own. It's a sleek, high-performance umbrella designed to withstand winds up to 72 mph (i.e. Force 11 winds), which basically includes everything below a hurricane.
The canopy is made from quick-drying polyester, and because of the frame's design — which uses what the company calls their Radial Tensioning System (RTS) — it's also super tightly tensioned to keep the umbrella from flapping, tearing, or turning inside out except in the most extreme conditions. The fiberglass shaft is durable as well, without adding a lot of extra weight.
