Mountain weather can be pretty dynamic, bluebird one moment, grey bird the next. When heavy clouds roll in and out faster than a lift line, the Radium Prime Sigma’s photochromic lenses mean you won’t need to make a swap. With a gradual shift from light to dark, photochromic lenses are a great pairing with temperamental conditions. And this pair comes with an extra light coloured lens, great for days with no sun in the forecast, or night skiing.
