The visor is injection molded from resin that offers UV protection. It' complies with ECE/UN 22-05: which requires verification of optical properties: visors must provide light transmittance greater than 80% ( clear visor), it is also allowed to light transmittance greater than 50% ( smoked visor) if the visor bears the words " daytime use only". Visors with lower light transmittance ( dark smoked visor) can be used for competitions at racetracks: for this reason, specific instructions are accompanied to the individual visor. The visor provides Scratch Resistant treatment on both sides. The blue metalized visor is not approved.
