For more aerodynamics Anti-fog, 4 magnets, smoked lenses MAGNETIC FIDLOCK: The magnetic buckle facilitates the attachment of the helmet. This feature effectively reduces triathlon transition times. Three air inlets are strategically placed where the air flow creates maximum pressure. Without creating turbulence, this provides good ventilation to avoid overheating.
