The Momentum ChromaPop Sunglasses--sharing a name with the force that lets our wheels fly downhill and our legs power through climbs--keep our vision sharp through every off-road ride. Smith designed these mountain-ready shades with a half-frame, toric lens, and ChromaPop technology to keep our field of vision wide and our visuals bright and clear. The wraparound fit features non-slip Megol pads that adjust to best fit our faces, offering security all across the singletrack.
