Details

• Product: Alpha by Bertoni Italy - TR90 frame, polymer structure made of Swiss material, extremely light and durable, weight 22 g. - Good coverage: wind and weather protection - better peripheral vision. The straight temples fit perfectly and comfortably under bike, ski, MTB and motorcycle helmets. The lens has a 100% UV400 protective coating. Wider lenses (52 x 140 mm) provide cycling and sports sunglasses a larger field of vision, windproof and curved design to protect you from air and bad weather.
• LENSES: Anti-fog Gold Mirror Photochromic Lenses: Starting from a clear condition suitable even in very low light conditions and darkening in bright sunshine up to category 3, they provide exceptional light transmission control (VLT 10-80%). The specially designed colour adjustment maximises contrast and improves visibility. Unlike conventional photochromic lenses, they darken by activating an external red mirror, improving glare, visual comfort in strong sunlight and the sporty technical look.
• SPRING/FLEX HINGES: They are known for their flexibility and offer a snug fit that doesn't squeeze. Unlike standard or barrel hinges, spring/flex hinges have an attached spring that allows a bend over 90°. The glasses hinge itself absorbs most of the force when the glasses bend, so this hinge type maintains its original balance and fit without the need for subsequent adjustment.
• MORE FUNCTIONS: Hyperflow cutting glasses that prevent condensation and thus increase air circulation and your comfort on both warm and cold days. The ergonomic, hydrophilic, soft nose pad provides an exceptional fit for any face shape. Thanks to their excellent grip on temples and nose pads, these sunglasses stay in place.
• INFO & ACCESSORIES: The package includes a semi-rigid case for safe storage, a cleaning cloth and a box. Lenses are optically decentred to eliminate distortion.
