The Smith Castaway are the long-awaited, do-it-all in all conditions sunglasses for the serious angler. No matter the aquatic objective, Smith's Castaway sunglass offers a real advantage thanks to the array of available high-end polarized lens options including NXT and glass with the vivid color and clarity of ChromaPop. A clever built-in PivLock leash retainer solves the riddle of quickly attaching (and detaching) the included sunglass leash. These premium Italian-made frames feature spring hinges and grippy megol nose and temple pads for a no-slip, extra grippy fit. An anti-reflective hydroleophobic lens coating ensures a return to crisp vision regardless of splashing or grime. Add more catching to your fishing with the Castaway.
