{"product_id":"smith-shift-split-mag","title":"Smith Shift Split MAG","description":"The Smith Shift Split MAG is a unisex performance sport sunglasses built for cyclists, mountain bikers, trail runners, and other outdoor athletes who need reliable eye protection across changing light conditions. The frame is constructed from high-impact-resistant TR90 nylon in a split, semi-rimless design — meaning the frame runs only along the top of the lens — delivering an unobstructed lower field of view and a lightweight feel. The lenses are made from polycarbonate and feature Smith's ChromaPop technology, which selectively filters specific wavelengths of light to improve contrast and color definition on road and trail surfaces. Lens options include photochromic clear-to-gray (20–80% VLT) for variable conditions, as well as fixed-tint ChromaPop colorways such as Black (10% VLT) and mirrored finishes for bright conditions.\n\nThe MAG system uses a magnetic-clip mechanism to connect the arms to the lens unit, allowing fast arm swaps without touching the lens surface and reducing fingerprint transfer. AutoLock hinges keep the frame open during one-handed on and off. Megol rubber nose pads and temple tips increase grip in wet and sweaty conditions, with two-position adjustable nose pads to dial in the fit. Each kit ships with a primary ChromaPop lens and a bonus clear lens, a hard case, and a soft pouch that doubles as a lens cleaner, providing light adaptability for early morning or after-dark conditions without carrying a separate pair.\n\n\u003cstrong\u003eKey Features:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eSplit semi-rimless frame design for unobstructed lower field of view\u003c\/li\u003e\n\u003cli\u003eHigh-impact-resistant TR90 nylon frame\u003c\/li\u003e\n\u003cli\u003eChromaPop polycarbonate lenses for enhanced contrast and color definition\u003c\/li\u003e\n\u003cli\u003eSmith MAG magnetic arm-swap system for quick, fingerprint-free lens changes\u003c\/li\u003e\n\u003cli\u003eAutoLock hinges for one-hand on and off\u003c\/li\u003e\n\u003cli\u003eMegol non-slip nose pads and temple tips\u003c\/li\u003e\n\u003cli\u003eTwo-position adjustable nose pads\u003c\/li\u003e\n\u003cli\u003eSmudge and moisture-resistant lens coatings\u003c\/li\u003e\n\u003cli\u003e100% UV protection (UVA, UVB, UVC)\u003c\/li\u003e\n\u003cli\u003ePhotochromic option: Clear to Gray (20–80% VLT)\u003c\/li\u003e\n\u003cli\u003eFixed tint options: ChromaPop Black (10% VLT), mirrored colorways (12–15% VLT)\u003c\/li\u003e\n\u003cli\u003eLens dimensions: 139mm wide x 60mm tall\u003c\/li\u003e\n\u003cli\u003e5-base cylindrical shield lens curvature with slight wraparound fit\u003c\/li\u003e\n\u003cli\u003eMedium to large fit\u003c\/li\u003e\n\u003cli\u003eUnisex design\u003c\/li\u003e\n\u003cli\u003eIncludes hard case, soft pouch\/lens cloth, and bonus clear lens\u003c\/li\u003e\n\u003cli\u003eRx prescription adapter compatible\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Smith","offers":[{"title":"Black | ChromaPop Photochromic Clear To Gray","offer_id":43425413627993,"sku":"SM-205883807992W","price":307.0,"currency_code":"USD","in_stock":true},{"title":"Matte Black | ChromaPop Black","offer_id":43444185661529,"sku":"SM-205883003991C","price":307.0,"currency_code":"USD","in_stock":false},{"title":"White | ChromaPop Violet Mirror","offer_id":43444185694297,"sku":"SM-205883VK699DI","price":307.0,"currency_code":"USD","in_stock":false},{"title":"Matte Tortoise | ChromaPop Photochromic Brown Opal Mirror","offer_id":43444185727065,"sku":"SM-205883N9P99GH","price":307.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0740\/4860\/2201\/files\/shift-split-mag-sunglasses_matteBlack-cpBlack_3Q-1_fixed.jpg?v=1781203843","url":"https:\/\/st1sports.myshopify.com\/products\/smith-shift-split-mag","provider":"ST1 Sports","version":"1.0","type":"link"}
