1. YEARS OF RESEARCH AND DEVELOPMENT - After years of designing and testing brollies, we understand everything that makes a great, durable and sturdy, wind resistant umbrella. There are four very important factors to look out for. 1) A STRONG FRAME WITH FIBERGLASS, 2) A STRONG CANOPY THAT'S BIG ENOUGH TO COVER YOU, 3) AN AUTOMATIC MECHANSIM ALLOWING ONE HANDED OPERATION and 4) EXCEPTIONAL CUSTOMER SERVICE YOU CAN RELY ON, EVEN AFTER OUR 30 DAY GUARANTEE. We explore these factors below. 2. 1) A STRONG FIBERGLASS FRAME - Our umbrellas are STRONG as we only use superior components and highly skilled Technicians. Our UltraFlex Frame Technology gives you both STRENGTH and FLEXIBILITY. Even if gusts reach 60mph, our design allows the umbrella to flip to regulate pressure. Then the ribs to their original position TIME AFTER TIME. This is what "Windproof" means; never settle for less. The frame has 4 layers, including our red support bars that give an extra layer of strength. 3. 2) A STRONG CANOPY THAT'S BIG ENOUGH TO COVER YOU - We only use HIGH QUALITY, WATERPROOF FABRICS that are strong, lightweight and flexible so they work in harmony with the frame. When open the canopy has a generous 60 inch arc and a 50 inch diameter, big enough to cover 1 or 2 people. 4. 3) AUTOMATIC MECHANISM - This umbrella opens automatically so you can react to a downpour in seconds. The great thing about an automatic mechanism is that you can open the umbrella with just one hand, very important when every second counts and you're carrying half a dozen shopping bags! When closed, the umbrella measures 39 inches from tip to handle.
