Climbing helmet, a Black Diamond Capitan in M/L size. Used only once for regular mountain climbing, and I am selling it because I no longer use it. There are no noticeable scratches, which are inevitable with use anyway. Many helmets tend to make your head look big, but I think this model looks smart. Retail price is 10,780 yen. The color is Astral Blue/Black. This is a climbing item, and I understand that there are no quality issues at this time, but I cannot be held responsible for any accidents caused by this product after purchase, so please understand this before purchasing. From the official website: A robust helmet that prioritizes protection of the sides and back of the head while ensuring a good fit and breathability. The two-tone shell has a two-piece ABS construction, allowing it to be molded to the shape of the head. The impact-absorbing foam combines EPP and EPS and meets the UIAA requirements for side and rear protection. It has sufficient openings and excellent breathability. Excellent impact absorption due to the two-piece construction of EPP (expanded polypropylene) and EPS (expanded polystyrene) High protection performance for the sides and rear Clean straps Headlamp clip integrated with the shell Removable inner pads Weight: S/M=285g, M/L=295g Size: S/M=Head circumference 50-58cm, M/L=Head circumference 56-63cm Thank you for viewing.
