Komine protector, size XL. Full support type. The size chart on the tag has disappeared, but as shown in the photo at the end, it has 7 cervical spine protector plates, so it's XL. I ride a motorcycle, but I mainly used it for MTB downhill. As a working adult, I can't afford to break any bones, so it's overkill, but I've used it dozens of times. I haven't fallen, so I think there are no problems other than the wear and tear from about 10 washes. If you have any concerns, please contact me and I will check again. Due to a job transfer, I haven't been doing MTB downhill for several years, and it's become tight due to muscle training, so I'm selling it.
