Review on Premium Windproof Travel Umbrella: Compact, Portable Folding Automatic & Strong Wind Resistant Double Canopy For Women & Men - Perfect For Backpack, Car Or Purse! by Christopher Shavers

It is rediculous to think all umbrellas are 100% windproof, and I had to wait for a day to rain to test this out obviously, but the moment I popped the umbrwlla open for the first time, it was already turning itself inside out on a gentle enough breeze. The vents may help disuade some of the air, but this seems more of a gimmick to me, now. No, really. This is only good to keep rain off you for a short walk from the store to your car, mot for ling term use. NOT WORTH IT.
