This is a Turn Me On amphibious nylon cap. It has only been used a few times, so it is in excellent condition! [Retail Price] ¥9,900 Side straps that reduce sun exposure. Adjustable. You can choose to attach them to the sides or to the back! The size can be adjusted with the velcro at the back. The top is made of mesh for good water drainage. The brim, which has no wire, is moderately stiff and does not get in the way even after a duck dive. This has already been tested, so I can definitely recommend it. I wore it for 3 days, 2 hours per round, with wave sizes from waist to chest high, and it never came off! Of course, it's not just for surfing, but also for SUP and general outdoor activities. It's light, so it's great for running too! For men and women, adults and children, it's an item that everyone can wear!
