Good sized glasses with side protection for high mountain use - this version has category 2-4 lenses that change according to the light conditions. Non-slip curved temples with Nose Grip so they stay on your head when things get bumpy, Air Flow ventilation and removable soft-feel side shields guarantee maximum comfort.

Photochromic lenses with high-speed activation and deactivation (cat. 2 to 4 - visible light transmission rate: 7% - 35%), they get darker or lighter to match changing light conditions and therefore adapt to any time of day. Internal anti-fog coating and external oil-repellent coating (prevents marking, makes cleaning easier and facilitates water runoff). Ideal for mountain sports, hiking, mountaineering, skiing, mountain biking, trail running and climbing.

  • Nose Grip - flexible, shock-absorbing grip insert on the bridge.
  • Air Flow - venting incorporated into the frame to facilitate air circulation and prevent fogging.
  • Cord attachment - allows attachment of a cord.
  • Curved temples - ergonomic profile for good grip on the face and head.
  • Fabric side shields - removable fabric, soft-touch side shields provide maximum comfort and do not cause irritation in contact with skin.
  • Grip Tech - exclusive soft-comfort material on the temples that doesn't stick to hair, giving perfect grip and comfort.
