Dee Gordon has been rocking Rooly flip-up sunglasses on sunny days, a brand that very rarely appears in the MLB, and is scarcely available at all. Judging by a brief search, Rooly almost seems like its out of business, so Dee must have pulled a few strings or did some digging to find his sunglasses.
Flip-up (or flip-down depending on your perspective) sunglasses are part of the fabric of baseball, and have been worn for decades. If you wear flip-ups you are automatically cooler. You can’t get the Roolys like Dee Gordon, but you can get the Gargoyle Gamer via Amazon at the link.
