The Bolle X9 OTG Goggles (Black/Vermillon Red) is a great looking pair of over the glasses/over the helmet snow or ski goggles. These goggles deliver the usual Bolle performance and protection, plus over-the-goggles and over-the-helmet functionality. The X9 is a medium/large fit.
The lenses of the Bolle X9 OTG Goggles (Black/Vermillon Red) use a Sport Optical System (S.O.S.), making them customizable with an optical prescription adapter (not included) that fits inside the goggles. A Double Lens Thermal Barrier is a unique design from Bolle that also provides exceptional optics and an outstanding seal. The lens technology in the X9 OTG uses P80 Plus/Carbo Glas for anti-fog/anti-scratch functionality. P80 Plus/Carbo Glas are a proprietary coating applied to Bolle's polycarbonate lenses and provide ultimate protection against unwanted interference and damage. Like all Bolle lenses, the lenses of these goggles prevent harmful UVA/UVB rays up to 400 nanometers.
The frame features Flow-tech venting to reduce fogging and optimize air flow over the inside of the lens. Venting ports control flow and prevent snow and ice clogging. Triple layer face foam, an ultra soft micro fleece material, is the only thing that touches your face, and it's backed by two layers of multidensity foam to provide a firm and soft fit. These goggles fit over most prescription glasses and are engineered with the latest helmet designs for a smooth fit.
