The Tifosi Veloce Fototec uses Light Night Fototec lenses with 75.9-27.7% light transmission. Fototec lenses adjust to ambient light in a 10 second transition time, helping your eyes adapt to existing light level conditions. The Veloce frame is molded from Grilamid TR-90, a flexible and virtually indestructible material characterized by an extremely high alternative bending strength, low density and high resistance to chemical and UV damage. The Veloce Fototec also features a fully adjustable nose pad and temples for a custom fit. In addition, the nose pad and temples are made of hydrophilic rubber that grips through sweat. Ventilated lenses increase airflow and reduce fogging. Includes carry case.
