STORM PROOF - Our wind resistant golf umbrella large will stand up to drops, falls, breaking and inverting. The Golf Umbrella & Golf Lite Umbrella are designed to withstand winds of 55mph. The Weatherman Golf umbrella is a big umbrella that is a perfect companion on the golf course. It is a heavy duty umbrella because of its industrial-strength fiberglass that prevents breaking and inverting, and vented canopies withstand winds up to 55 mph. It has UPF 50+ barrier that protects you from the sun. A large mesh pocket offers handy storage and a silicone-coated rib makes for a perfect place to hang your towel so it doesn’t slip off. Our umbrellas are guaranteed by a lifetime warranty that covers any malfunction or defect to the handle, frame, canopy, or anything else that functionally impairs the umbrella. If it breaks, we will fix or replace it for you. Please note that this guarantee does not cover natural wear and tear, misuse, and damages caused by improper care.
