At the outset of another rainy weekend, the ideal city umbrella poses something of a dilemma. You might balk at the prices of expansive, high-end versions, but those $4 deli umbrellas crumble at the first gust of wind. Combining the best of both worlds, Brit brand London Undercover makes a mini-umbrella that’s lightweight and purse-size, but impressively sturdy. Its CMYK range (with the choice of a cyan, magenta, yellow, or black handle) is made out of recycled PET fabric and comes in a recycled tube. But the real draw is the windproof design, which prevents it from flipping inside-out on your walk from the subway.
