Stepping away from the signature Spektrum monochrome colour palette the Duo-Tone Series marks a shift in our company’s direction. Not so much the obvious two coulured frame but the material of which these frames are built is something very special. Having lived our whole lives in the mountains we have seen the impact mankind has had on our nature first hand and we are determined to minimize the footprint of our actions. For the Duo-Tone series we have worked closely together with Sweden’s leading scientists and the Sports Tech Research Center at Mid Sweden University finding new materials and ways how to make things in a more sustainable way. Together we have strived to find the best possible substitute for the oil based polymers and materials found in traditional goggles and our efforts have been realized in the Duo-Tone series. Using new plant based polymers derived from castor and ricin oils as well as recycled polyester.
