Pursue your thrill in the backcountry. From skin track to boot pack to full-speed descents, the Smith Pursuit sunglasses can do it all. They blend goggle-like coverage with the airflow and easy-to-wear feel of sunglasses that perform while you're climbing and descending. Our ChromaPop™ Glacier Photochromic lens adapts to changing light conditions and delivers color and contrast-boosting performance throughout the full range of the lens. Removable, magnetic side shields add peripheral light coverage, and adjustable temple arms let you customize the fit. A pack-friendly, screwless hinge creates a fail-safe backcountry design, and a low-profile case ensures minimal storage in your pack. </br></br> <b>Fine tune your kit with additional or replacement lenses for sunny conditions, variable conditions, and cloudy conditions. <a href="https://www.smithoptics.com/en_US/p/lens/pursuit-replacement-lens-replacement-lens/PURSUIT-REPLACEMENT-LENSES.html" title="Go To Pursuit Sunglass Replacement Lenses"> Expand your view here.</a></b>
