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. The 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.
