arena Swimming Silicone Cap Color: All colors are shown in the photos, either dark navy or navy blue. Size: Free size As it's for competitive swimming, I thought it would be a sturdy material. I bought it a few years ago and used it twice, but it was too tight when I put it on, so I just left it unused. Maybe it would be better to wear a net cap underneath... There are no noticeable scratches, but please check the photos and consider. ・I'm also selling another one.
