Sturdy windproof automatic umbrella built to withstand strong wind and heavy rain. It combines a lightweight aluminum shaft with reinforced fiberglass ribs (12 pairs) for a durable, stable frame. The high-density canopy stays taut and flexible, adapting to bad weather without easily overturning. Size and weight: 46 inch arched canopy provides spacious coverage for two. Folds to 12.7 inches and weighs 17 oz. The 12 pairs of fiberglass ribs contribute to the slightly heavier feel, and the vinyl sunscreen design is a noted feature. Material and performance: The canopy is made of 210T pongee, highly water-repellent and quick-drying. After closing, shake gently to remove water. The handle is about 4 inches to fit typical usage habits. Automatic operation: Open and close with a simple press of the button for one-handed use, so you won’t get wet when entering or leaving a car. Use scenarios: Ideal for commuting to work, everyday travel, and weekend trips. Easy to slip into a backpack for on-the-go protection, or give as a practical gift to friends and family, including college students during Christmas.
