This is a silicone cap provided at a triathlon event. Although there is no logo, the brand is TYR. The second photo shows the cap inside out, but the design is the same as the front. I have also included a photo of the inside as the third image. It was only used once on the day of the event and has been stored in my room for many years. I wiped the surface dirt with an alcohol wipe and disinfected the inside, but there may be some fine dirt remaining if you look closely. If you are concerned, there is no mold invasion, so I think it will become even cleaner if you wipe it. I have confirmed that there are no issues with wearing it again, but please understand that due to aging, it may tear more easily than a new one if excessive force is applied or if you use your nails. Overall, I believe it is in good condition. I think both men, women, and children can use it for swimming.
