The Davek Golf is our largest long-shafted umbrella, featuring a massive 60-inch arc diameter canopy. The Golf's exclusive "Duplex Frame" dual-canopy design navigates wind through its vented construction. The umbrella has been windtunnel-tested at MIT Aeronautics & Astronautics and guaranteed to endure gale-force winds of over 60 mph. An extremely strong fiberglass shaft gives the umbrella unsurpassed stability. Rotate the umbrella handle's base to expose a sleek aluminum-alloy "anchor spike". Push the spike into the turf to keep your open umbrella in place while taking your golf shot. And, once the open umbrella is anchored, individual clubs can be propped against the ribs to keep them upright and dry while you take your shot. The Davek Golf is not only for golfers! It makes an ideal choice if you are looking for maximum coverage in any storm.
