We all remember our first day without training wheels on the bike. Mom decked us out from head to toe in padded equipment, and somehow, we still ended up with a few raspberries that hurt to this day. But now, you're older and making your own choices about safety. Whether you're a safety-first or a safety-third kind of rider, everyone can agree that a good pair of mtb sunglasses is a vital part of any kit. Since we know how important your shades are, we gathered together our favorite photochromic and polarized sunglasses in one place to help you go faster and look cooler, all while protecting those peepers.
