The foam layer is injected directly into the hard outer shell. Polycarbonate is the material used to manufacture the helmet shell. The polycarbonate shell is firmly bonded to the EPS inner material. The EPS material is injected directly into the polycarbonate top layer, creating an integral unit. This monolithic unit absorbs localized impacts from sharp objects, and the force acting on the helmet is distributed across its entire surface, ensuring perfect protection for the head. FAS is a quick adjustment system that forms a network of straps anchored inside the helmet. It allows for a tighter and more secure fit of the helmet on the head. The sophisticated IAS-3D system enables good adjustment of the helmet size to different head sizes and shapes by simply turning the adjustment dial. The interior of the helmet adapts to the height and circumference of the head.
