The HELIUM ALK13 helmet uses Inmold technology:
the fusion between the outer shell and the polystyrene limits the thickness and weight of the helmet, giving it a more streamlined design.
One helmet, two sizes thanks to the additional foams provided in the box and a perfect fit to each with the help of the straps.
