With In-Mould technology, the external polycarbonate shell is moulded during the expansible polystyrene (EPS) injection stage. This resulting structure is much stiffer, very durable, and extremely light. The inner EPS structure absorbs the energy generated during an impact, while the stiff outer shell ensures greater durability.
