The Giro Axis gives any skier and snowboarder a huge field of vision and the ability to swap out lenses in a matter of seconds. Giro's Vivid Lens has been designed by Zeiss Optics to improve your contrast and definition of the snow. Vivid Lenses will reduce the strain on your eyes and improve your reaction time, especially when the light gets tricky on you. The Axis also features Quick Lens Change Technology that uses magnets and snap pins that is extremely simple and easy to do in between laps on the chairlift. The EXV (Expansion View Technology) opens up your peripheral vision on the slopes for a safer and more scenic ride down. Evak Vent Technology is made from foam that that is very durable and will not absorb moisture to reduce the chances of your lenses fogging when you start getting warm from ripping so hard.
