Crown Liner Padding for Zamp FR-4 Helmets. These pads replace the internal front crown and head lining for the FR-4 helmet, and is ideal for the top areas of the helmet when original padding may be oversized, undersized, or compromised by dust and debris, or sweat. 

One advantage Zamp helmets is the replaceable padding material in each helmet, like this padding. 

Padding is available in a variety of padding sizes for a variety of helmet sizes.
