Mercer is all in the details. From afar it may appear a familiar shape, but up close the structure hosts a complex identity with slanting ridges and boxy refinements. Enlarged temples give Mercer a commanding side angle, complimented by titanium x emblems in a one-of-a-kind design. Mercer is built from custom dyed bio acetate and fitted with 100% UVA and UVB protective lenses.
