SHWOOD X IRON & RESIN Just like our bikes, we believe our gear should perform as good as it looks. This shared appreciation for the balance of style and utility brought us together to create the ultimate moto glasses. Inspired by the originality living within our bikes, the glasses reflect a raw yet refined aesthetic and the functionality to get us where we need to go. These limited edition glasses feature our custom Memory Metal clip-on polarized lenses. That means an easy on-and-off functionality that will easily keep 'em there while rippin' through the wind. Each raw steel clip-on has been individually flame-tempered for a one-of-a-kind brazed steel finish. They're also incredibly lightweight so you don't have that heavy feeling on the bridge of your nose.  Simple and effective...Just how we like it.
