Bike helmet size guide:
Ski helmet made in France for winter sports and car enthusiasts. DIEZZ and ALPINE have joined forces because the two brands' philosophies of performance, safety, and Made in France are perfectly aligned.
Thanks to DIEZZ Activlux photochromic 1 to 3 technology, your screen adapts to all weather conditions.
No need to change screen according to brightness, the tint of your screen adjusts automatically thanks to a treatment integrated into the heart of the material to offer you the best UV protection, as well as perfect visibility. The range of protection adapts equally well to overcast, end-of-day conditions (category 1) and sunny, bright conditions (category 3). For optimum comfort and fit, the screen is fitted with triple-density thermoformed foam.
