A material used in Smith helmets that provides a high level of safety. It is characterised by a cylindrical structure that absorbs energy during impact and transforms it into kinetic energy, but does not give it back, as is the case with materials that act like a spring. In addition, thanks to their construction from small tubes, they are well permeable to air.

Hi-EPS is an innovative technology used in Alpina helmets, whose microscopic air chambers effectively absorb the forces generated during impact. Thanks to the use of Hi-EPS, the helmets offer optimum protection while remaining slim and thin-walled for increased comfort.

In-mold is a manufacturing method in which the outer shell of the helmet is permanently bonded to a layer of inner protective foam during moulding. This makes the helmet lighter, more durable and better absorbs impacts. The process also provides an aesthetically pleasing finish and increased structural durability.
