The Signature Series features rider endorsed models by Devun Walsh, Mikey Leblanc, Wille Yli- Luoma, Tadashi Fuse, Chris Dufficy 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 a “bonus” secondary rose lens. This series is helmet compatible.
