When the backcountry calls and conditions change faster than your next turn, the Smith Pursuit ChromaPop Photochromic Sunglasses deliver the adaptability you need from skin track to summit. These alpine sunglasses blur the line between goggles and glasses, offering goggle-like coverage with the breathability and lightweight feel that backcountry skiers and mountaineers demand. The ChromaPop Glacier Photochromic lenses automatically adjust from bright alpine glare to flat light conditions while enhancing contrast and color definition, so you can focus on your line instead of fumbling for different eyewear. Magnetic side shields snap on when you need peripheral protection during exposed traverses and pop off easily when you're moving through trees or want that classic sunglasses feel. With screwless hinges that eliminate the weak points that plague other mountaineering eyewear and an interchangeable lens system for fine-tuning your kit, the Pursuit sunglasses are built for adventurers who refuse to compromise on performance when the mountains get serious.
