Our design ethos has crystallized into its ultimate form with this new addition to our vaunted ?M Class X2? collection, 'Crystal Wave.' The half-transparent frame is a matte-finished cool gray on the exterior, while the interior pops with a gloss peach treatment for a satisfying color contrast. The polarized champagne lenses play perfectly alongside the peach accents, bringing a slick, sublime cohesion to this style. Even better, the whole package is backed by the elevated engineering of this upscale collection?next-level spring hinges, all-metal temple stripes, and laser-etched lenses are all included.
