NEW! The same great function as the original Caso Nordic Eyeshield but with a smaller profile. Combining CASCO’s patent pending technology and the original “best of test” CASCO NORDIC, the refined, new CASCO NORDIC SPIRIT is attractive and fashionable. The SKIsport Magazine in Norway rated: “Not only Biathletes love this specialty eyewear. Different from other Sunglasses, this eyewear doesn’t fog up. The lenses protect from heavy snowfall, cold and sun, where usual sunglasses give up at these 32 conditions. You’ll feel the difference!” Vautron(tm) polymer lense. Vautron is a unique optical polymer unlike any other. Originally developed for military purposes and used in AH-64 Apache helicopter windshield panels. Photochromic, super scratch resistant, lightweight, and optically superior!
