With a maximum weight of 165 g, the SIROCCO helmet is the new world standard of lightness in climbing helmets. The monobloc construction minimizes helmet weight while retaining excellent impact resistance, due to the mechanical properties of expanded polypropylene (EPP). The textile-based adjustment system also contributes to its lightness. This helmet comes with a new magnetic buckle which allows the chinstrap to be attached with one hand. The SIROCCO helmet also has excellent ventilation distributed around the helmet.
