Fulton's lightest and sleekest umbrella ever, the Aerolite is constructed to offer superb weather protection without a gram more weight than necessary. The entire thing is built to fight wind and rain, with a frame that can withstand stiff winds without inverting and waterproof, ultra-light polyester fabric. When opened it offers 83cm of rain cover but folds down to 20cm when closed. Fulton Aerolite Folding Umbrella | Ultimate Outdoors
