Take on bright mountain conditions with confidence in the GOG Tatra Outdoor Sunglasses. Designed for glacier and high-altitude environments, they combine strong light protection with a lightweight frame in a striking Matt Grey/Neon Lemon finish. Their secure fit and advanced lenses make them ideal for demanding outdoor use.
Equipped with a UV400 filter, the lenses block all rays up to 400 nanometres for full sun protection. The photochromic design adapts to changing light, darkening under stronger sunlight to maintain comfortable visibility. A colour mirror coating helps reduce reflections and enhances clarity, while the hardened surface improves scratch resistance for reliable long-term performance.
With filter category 4, the lenses allow only 3%-8% of visible light through, offering maximum protection in intense sunlight often found on glaciers. (Not suitable for driving.) The Rilsan G850 frame is durable, flexible and lightweight, making it comfortable for extended wear. A hard case is included to keep the sunglasses safe when not in use.
