Z-20 Photochromatic - Anti-Fog Dirt Shield

ZAMP Z-20 Photochromatic Shield - Dirt & Anti Fog Exclusively from Zamp Racing! Photochromatic Dirt Anti-Fog Shields. To prevent dirt from packing in between the top of the shield and helmet, these shields utilize rubber trim across the top to help seal the shield tight to the helmet. Go from bright to dark racing conditions without having to change shields! The new Z-20 Photochromatic Anti-Fog Shield smoothly transitions from clear prism to red prism, blue prism, or dark smoke (or vice versa) depending on the brightness of the track, without having to change the shield! One shield works for Night or Day Spare and replacement helmet shields are important to have for the serious racer or track day enthusiast. 3mm thickness, 12.125 inch tear off post centers. Fits all ZAMP RZ Series Racing helmets with the SA2025, SA2020 certification.
