COLLAR AND CUFFS LONDON - RARE 2-Fold Windproof - 50 inch Arc - EXTRA STRONG Folding Umbrella - Vented Canopy - Auto Black 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 FIBER GLASS, 2) A STRONG CANOPY THATS 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. 1) A STRONG FIBER GLASS FRAME - Our unique 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 50mph+, our design allows the umbrella to flip to regulate pressure. Then our fiber glass ribs return to their original position TIME AFTER TIME. This is what windproof means; never settle for less. Each rib and stretcher are highly engineered to give you RELIABILITY. 2) A STRONG CANOPY THAT'S BIG ENOUGH TO COVER YOU  This umbrella has a VENTED DOUBLE CANOPY designed to regulate pressure. Two overlapping canopy layers have vents which allow gusts of wind to pass through the umbrella reducing the risk of inversion. 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 50in arc with a 42in diameter. 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 youre carrying half a dozen shopping bags! When closed, this umbrella measures 18in from end to end, making it ideal to store in a rucksack or larger bag. 4) EXCEPTIONAL CUSTOMER SERVICE - Buy with confidence with our money-back guarantee. Our after-sales support is world-class, no matter how long you've had the umbrella, always get in touch if you need us and we'll do our best to help. We never take your custom for granted; we have many loyal customers who come back to us again and again as we look after them!
