The Signature Series features rider endorsed models by Tadashi Fuse, Chris Dufficy, Mikey Leblanc, Wille Yli- Luoma, and Kale Stephens. This series is available exclusively in the Forma frame and offers luxuries such as triple layer face foam for better fit and comfort as well as R-Tex mesh, which prevents ice and snow from blocking vents holes. All Signature Series frames come equipped with rider specified spherical mirror lenses and an option to upgrade to an extra secondary rose lens.
