Like the rest of the SR4105 line, this pair folds down via a hinge built into the square plastic frame, sized at a 50mm eye and 140mm temple. The lens is UV400 polycarbonate, with tint choices spanning solid colors, gradients, mirror coatings, and a photochromic finish.

The matte coating on this version flattens the surface finish so it doesn't catch a shine the way a standard black frame does, and that lack of gloss also hides the light surface scuffs and fingerprints that build up on a frame you fold and unfold daily. It's the better pick if you want the black colorway without the upkeep of wiping down a glossier finish.
