Product: Kask Protone Icon Size: M Condition: Only tried on indoors. Purchased in mid-August of this year. I prepared to use it the other day, but it was too tight, so I stopped. In the second photo, the area where the name sticker was placed is blacked out, but it will be removed before shipping. *Please rest assured that there will be no marks left. I have used Kask Protone helmets in the past, and it was the best in terms of lightness, fit, and peace of mind. This time, I purchased a successor to the model I had used in the past from a professional shop in Japan, in the same size and color. However, I no longer participate in races, and my hair has grown longer, making the M size a bit tight, so I am selling it.
