This helmet’s 16 internal airflow channels, combined with vents, help wearers keep a cool head.

With in-mold technology, the external polycarbonate shell is moulded while expandable polystyrene (EPS) is injected. The resulting structure is harder, sturdier and extremely light. The inner EPS structure absorbs the energy of impact while the hard outer shell ensures durability.

In-mold technology and EPS
