Smith designed its Attack Max ChromaPop Sunglasses for cyclists that aren't always the most willing to hang back in the pack. Their aerodynamic profile and streamlined designed are better suited to leading the peloton than drafting towards the back. Aerodynamics aside, the Attack Max Sunglasses also offer cyclists a crisp field of vision thanks to ChromaPop technology. Smith's flagship lenses reduce color confusion while filtering harmful UV rays for a crisper field of view and better color contrasts. The actual shape of the lenses increase the coverage area for added protection from wind, light, and debris, and the frameless front is designed to integrate with Smith cycling helmets for a gap-free fit and enhanced ventilation. These sunglasses are equipped with Smith's quick-release MAG interchangeable system and come with an extra pair of ChromaPop lenses to accommodate different light conditions.
