HJC C10 Size: M Manufacturing Year: 2023 Some scratches on the exterior. The interior is in good condition with little wear. Includes both a smoke and a clear shield. Racing spoiler, breath guard, and smoke shield were recently installed. They have only been tried on since installation. The interior has been washed for this sale. Regarding the fit, I wear M size in both ARAI and SHOEI helmets, and this helmet fits the same. As a bonus, I will also include a center pad for size L.
