Double Layer Windproof Auto Umbrella for Rain Car

This 21-inch auto open and close 3-fold umbrella is engineered as a professional defense tool against harsh weather conditions like strong winds and heavy rain.  Its core advantage lies in a unique 8-rib support structure and a double-layer canopy, working together to create an exceptionally stable protective dome.  Combined with a one-button automatic function, it enables you to quickly secure reliable shelter in storms.   The frame utilizes a composite scheme of "1 aluminum rib + 2 fiberglass ribs + an iron shaft" to ensure overall rigidity.  While the use of more robust materials for ultimate windproof performance results in a weight of 384g, its folded size of 28*6.5*6.5cm maintains good portability.  It is an ideal choice for users who demand absolute reliability and for the corporate gift market, standing out as a premier Auto folding umbrella and a truly reliable Windproof travel umbrella.        1.
