Diezz Nemesis S1-3: a ski helmet with a visor for those looking for a combination of comfort and ergonomics

Every detail of the Nemesis is designed for long-lasting comfort.The synthetic micro-fur interior and soft ear pads provide softness and thermal insulation, while the adjustable vents allow you to adjust the airflow to suit your needs. The FIDLOCK buckle makes it easy to put on and take off the helmet, even with gloves on, for added convenience on the slopes.

ActivLux photochromic lens for all conditions

The Nemesis S1-3's standout feature is its ActivLux 1 to 3 photochromic lens. It automatically adapts to light conditions, offering optimal UV protection and perfect visibility:

  • Adjustable tint range from category 1 to 3, for transitioning from overcast to bright sunshine
  • Red mirror iridium coating, anti-micro-scratch for maximum durability
  • Triple-density thermoformed foam for comfort and a perfect fit
  • Panoramic field of vision, reducing blind spots and improving slope perception

Durability and responsible design

Designed to last, the Nemesis is fully repairable: visor, adjustment system, ear pads, and buckle can be easily replaced. This design extends the life of the helmet and reduces its environmental impact, while ensuring consistent performance season after season.
