Updated version of the excellent Category 2-4 mountaineering glacier glasses. Ideal for alpine and general use, they adjust to suit the light meaning they can be safely worn for anything from glacier crossings in blazing sunshine to ski mountaineering in a white out.
Perfect for small to medium faces, the removable protective side shields give good adaptability depending on what one is doing and the conditions one is doing it in. They also have newly designed Grip Tech temples and a non-slip bridge.
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.
- Ergonomic profile for good grip on the face and head.
- Exclusive soft material on the temples that doesn't stick to hair, for perfect grip and comfort.
- Flexible, shock-absorbing grip insert on the bridge.
- Removable side protection from sunlight - can be fitted for extreme conditions.
