This is a SWANS ski and snowboard helmet, a free ride model, unisex H-45RM GMR gun metallic, size M (head circumference 52cm~58cm), as seen in the photo. It is new, only tried on. The Amazon description says it's for adults, but it's probably for children. How about a Japanese-made helmet for your child's safety? By the way, the Amazon price is 7,920 yen. I am also selling a size L, used only for two days. Bundling is welcome. I will wrap the original box in plastic and ship it from Saitama. Thank you!
