With a massive 60-inch arc-diameter canopy, the Davek Golf offers shelter from the storm and then some. The Golf's exclusive Duplex Frame dual-canopy design navigates wind through its vented construction. The umbrella has been wind tunnel-tested at MIT's Department of Aeronautics Astronautics, and is 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. Not restricted to golfers, this umbrella is an ideal choice for anyone seeking maximum coverage in any storm.
