If Rihanna didn't make umbrellas cool, The Brelli ($28-$38) mos def does. The Brelli is made from bamboo, which is sustainable and a clear, biodegradable canopy, so the entire umbrella will completely biodegrade within five years when discarded. Considering how many nylon and plastic umbrellas I lose track of, and which probably make their way to a landfill somewhere, I think this is a great idea. But, the Brelli elli elli is so chic and functional looking, the thought of it decomposing kind of makes me sad, in a way. Aside from being the world's first 100 percent biodegradable umbrella, it's probably the only umbrella I'd be able to hold onto 'cause it's so darn striking.
