Frame Tech: B88™ Nylon - Bollé® uses only the finest grade nylon, resulting in frames that are exceedingly strong, yet lightweight and flexible. Thermogrip Temple Tips And Nose Pads - The comfortable hydrophilic nose pads and temple tips maintain your Occhiali da sole in place and let you concentrate on what you're doing, rather than on your glasses. Adjustable Nosepieces - The shape and angle of the multi-plane nosepiece can be adjusted to accommodate any nose bridge for a truly custom fit. Lens Tech: Oleophobic/Hydrophobic Treatment - The hydrobhobic and oleophobic applied to the inside lens surface protect you from the rain and damp and prevent finger marks from forming. Anti-Fog Treatment - No fogging on your eyewear under any circumstance. Not only repels the fog that clouds your vision but is simply revived by an application of moisture. Polarized lenses have a filter within the lens that blocks the wavelengths of light that cause glare. Bollé® photochromic technology is embedded into the lens at a molecular level to automatically lighten and darken according to the conditions, always protecting your eyes from harmful UV rays.
