The frameless design on these ski goggles looks great and lush. Even the heavier spray will glide easily off the goggle without sticking to the frame or affecting your sight. The mirrored lenses of these retro ski goggles not only look cool, but also offer complete protection from infra-red rays. The variomatic lens technology automatically reacts to every light situation. The photochromic lenses dose the shading in three levels of protection, from S1 to S3, according to the light conditions. Of course, all lenses provide 100% protection from UVA, UVB and UVC rays.
