Description The SIROCCO is designed to respond to the needs of climbers and mountaineers for reduced weight and for protection. Its head-covering shape, lower in the rear, offers enhanced protection over the entire head. Optimized volume on the head, along with excellent ventilation, provides maximum comfort. SIROCCO is also suited for ski touring, thanks to its CE ski touring helmet certification. This helmet does not meet the requirements of the EN 1077 standard for alpine ski helmets.
