AGV k6 K-6 M size Manufacturing year: 2022 I haven't worn it much, and have been storing it. Therefore, both the exterior and interior are in good condition. I have adjusted the sponge padding around the head. I washed the interior for the listing. The shields are clear, smoke, and red mirror. Regarding the size, I usually wear M size in ARAI and SHOEI, and this helmet feels the same size.
