Optics by Carl Zeiss
Creators of some of the world's most advanced optics, Optics by Carl Zeiss Vision bring incredible quality and experience to the optics of K2 Goggles. Each lens is made of a tough polycarbonate and treated with a hard-coating for superior performance and extreme scratch resistance.


Ri-PelĀ® is a proprietary hydrophobic vacuum coating that is applied to each one of our Optics by Carl Zeiss Vision K2 lenses. Designed to minimize scratching and smudging, expel residue from water, sweat, and fingerprints, and enhance overall visibility, Ri-PelĀ® offers the necessary lens protection required by today's riders.

Helmet Compatibility

Helmet Compatibility
Through the helmet-driven topline design and custom engineered strap brackets of each frame, K2 goggles achieve maximum fit and ventilation with all K2 helmets. The addition of lens vents that work in harmony with K2 helmets' venting systems minimize moisture buildup and maximize air circulation to ensure a clear field of vision and optimized temperature control. Silicon-backed goggle straps keep your goggles firmly in place when charging the most aggressive lines.

Triple-Layer Fleece-Lined Face Foam

Triple-Layer Fleece-Lined Face Foam
Custom fabricated, triple-layer fleece-lined face foam delivers consistent comfort and allows for close face-to-lens proximity, maintaining ultimate pantoscopic angle.

Pantoscopic Angle

    Comments about K2 Skis Sira - silver:

    FINALLY - a goggle that fits, stays put, and I CAN SEE. First: FIT - made for a woman's smaller face and fits snugly with my K2 Virtue helmet. It didn't slip down (yea!) I'm a ski instructor so it's important that goggles stay put so I can focus on other things. Second: USE - wore these on a Sunny/Partly Cloudy day, early season so I was moving between shade and sunlight regularly. Loved that I didn't have to "hope" in the shade that there wasn't any surprises - I could SEE! Not only can students see my eyes, but I can see them and the conditions clearly! Did I mention I could SEE??? And see CLEARLY! STOKED!!!
