Ski and Snowboard Goggles GIRO SAGEN DARK SHARK THIRDS with Grey Cobalt S3 and Yellow S1 lenses

GIRO SAGEN DARK SHARK THIRDS goggles are designed for skiing and snowboarding and include two interchangeable lenses: a Grey Cobalt lens with 8–18% visible light transmission (S3) for bright, sunny conditions and a Yellow lens with 71% transmission (S1) for low-light or overcast scenarios. The frame provides full-face coverage and compatibility with most helmets, while the lens system supports quick swapping on the slope to adapt to changing light. Materials and construction focus on impact resistance, optical clarity and a comfortable fit for extended use during alpine, resort and freeride sessions.

Advantages

The two-lens system offers versatile performance across a wide range of lighting, reducing the need to carry additional eyewear. The Grey Cobalt S3 lens reduces glare and preserves contrast in bright sun, while the Yellow S1 lens enhances contrast and visibility in flat light. The frame geometry and strap design ensure stable fit with helmets, and the lens interchange mechanism enables fast, tool-free changes. Anti-fog properties and ventilation channels improve airflow to maintain visual clarity during physical activity.

Suitable for

• Downhill and alpine skiing in varied light conditions
• Freeride and off-piste skiing where quick lens changes are needed
• Resort and park riding with helmet-compatible fit
• Low-light or night approaches using the high-transmission S1 lens
• Bright, sunny days using the low-transmission S3 Grey Cobalt lens

How to use

Select the lens appropriate for current light: install the Grey Cobalt S3 lens in bright, sunny conditions and the Yellow S1 lens in low-light or overcast situations. To change lenses, follow the frame’s quick-release method—carefully disengage the lens from the frame edge, align the replacement lens into the frame groove, and press until it locks. Ensure the strap and foam sit comfortably against the face and that the goggles are compatible with your helmet before riding. Store lenses in a soft pouch or case to avoid scratches when not in use.

Usage recommendations

Clean lenses with a microfiber cloth and use anti-fog care as recommended by the manufacturer; avoid touching the inner lens surface to preserve anti-fog coatings. When switching lenses frequently, handle by the frame edges and store the unused lens in protective packaging to prolong service life.
