Description Born of the same everyday adventure recipe as the Overtone, the Smith Overtone Slim scales back the coverage a bit to work well with smaller-size faces. This classic rectangular shape adds a 6-base lens curvature that provides a modest wrap to the fit. Add the adjustable wire-core temples and you have a fit and feel that lets you be active without worrying about your glasses. Bio-based injection-molded frames maintain lightweight durability that's up for everyday wear and road trips alike. Smith Optics proudly assembles select products in our Clearfield, Utah facility, part of a nearly 60-year commitment to expanding U.S. operations and innovation.
