The Altona M scores with its mirrored visor and excellent damping and ventilation properties through the Koroyd technology. The stable and extremely lightweight honeycomb structure consists of a large number of small tubes that are thermally connected to each other. In an impact, they deform flat and absorb energy. The sturdy construction allows Koroyd also greatly enlarged openings in the helmet surface, which guarantee excellent ventilation. Ventilation ducts guide the air in the interior along the head. The self-tinting (photochromatic) disc reacts to UV light and darkens automatically. The light silver mirroring reflects infrared rays, giving 100% UV protection at all times. Additional plus: behind the visor and optical glasses have enough space.
