Both Zamp Z-21 and Z-20 series shields are compatible with the RZ-48Y Carbon Graphics Youth Racing Helmet. The Z-20 shield is standard on all SA-rated helmets, offering greater thickness and strength for higher impact protection, while the Z-21 shield is lighter, aligning with the Snell/FIA CMR standard for youth helmets.
