Keep it in your car for sudden storms and have it for long walks in the rain.Cover yourself from the rain with our windproof 10 rib compact umbrella. Unlike similar umbrellas with 6 or 8 ribs, our 10 fiberglass ribs hold steady in strong gusts of wind, and the Teflon coated 300T Pongee(best fabric ever used in umbrella) canopy provides superior wetness and UV protection.
