Glacier goggles with interchangeable lenses for ski touring and alpine activities. The American (bike) eyewear and helmet specialists at Smith Optics are known for their high-quality products, and the Pursuit Mirror S3 (VLT 12%) + S1 (VLT 89%) is no exception. The lenses provide good protection, and thanks to ChromaPop technology, contrast and natural colors are enhanced, allowing you to perceive details better. Whether you're going uphill with skins on your skis or racing downhill, the Pursuit reliably accompanies you and lets you see things clearly; magnetically attaching side shields offer additional protection for your eyes against overly bright light. Included are two lenses, one for sunny days and one for darker days, each falling into protection categories S3 and S1 respectively; also included is a transport bag for the lens not in use and a practical, flat-profile glasses case.
