In-Mold moulding technology and EPS

The In-Mold moulding technology used in manufacturing this helmet makes it possible to mould the external polycarbonate shell during the expansible polystyrene (EPS) injection stage. This results in a structure that is much stiffer, very durable, and extremely light. The inner EPS structure absorbs the energy generated during an impact so that it is not transmitted to the skull, while the stiff external shell provides the helmet with longer-lasting durability.
