We have worked closely with an industry leading anti-fog hard coatings company to develop a proprietary, goggle specific, anti-fog technology. We also tirelessly sourced the most durable, scratch resistant lens materials as well. The result is an innovative Italian sourced, dual pane lens. This new technology provides an unmatched ant scratch rating for both the inner and outer lens. In addition, we applied an additional, dual coated NO SCRATCH, hand applied hard coating. This protective, permanent hard coating provides an unmatched level of scratch resistance to your goggle lens.
