The Giro Index Goggle is the perfect solution for those who need vision correction while skiing. Featuring the OTG (over-the-glasses) technology frame, superior fit is assured thanks to temple cutouts for eyeglass frames, and double layer face foam with microfleece facing for boosted comfort. High-performance, injection-molded cylindrical lenses and optional VIVID lenses with Optics by ZEISS® provide superior visual clarity.
