The next great wave of Bro inventions will be in the cheap sunglasses space. A few weeks ago I told you about interchangable Kenny Powers/Riff Raff sunglasses all over Amazon. Then last week, “impossible to lose” sunglasses with magnets in the frames made the rounds on Kickstarter. Next up: The Hilx, a pair of shades that automatically unfolds with a little snap of the wrist. They look great, too, which makes them one of the best sunglasses on the market.
