Sutro eyewear has announced the launch of the Hetfield, a limited-edition sunglass frame that is the product of a design collaboration with James Hetfield of METALLICA.The Hetfield is a classic shape with a rock-star edge. This frame is as smooth and as fast as James' Lincoln Zephyr v12. Using Zeiss optics and the Sutro stainless steel 3Click hinge, this frame is designed to take whatever a 24-stop Eastern European tour can throw at it. It will not lose screws, is 10 times stronger than a traditional hinge and gives the frame a structure that stays tight over time. Zeiss polycarbonate lenses block 100 percent of both UVA and UVB sun rays and provide the ultimate in impact resistance with the industry's toughest hard coating for superior scratch resistance. These limited-edition frames are road-worthy and built to last! "Built to look faster than a speeding riff and to handle the life of a road dog like me," says James. "James was very particular in what he was looking for and he just wasn’t finding it out there, so we sat down and after extensive prototyping we put his vision into this frame," says designer Jeff Sand. Founded in 2006, Sutro produces durable luxury eyewear in both sunglass and optical frames. Sutro eyewear is currently available through boutiques and specialty retailers in the U.S., Japan and Germany. For more information, visit Metallica.com.
