Thank you for viewing. Only tried on indoors. I haven't had a chance to go fishing since I bought it, so I've been storing it. Product Information ■ Tournament cap with D.D.SYSTEM for easy adjustment Equipped with D.D.SYSTEM (Direct Dial System). With a simple dial operation, you can easily, quickly, and with one hand adjust the fit, allowing you to respond instantly even when hit by strong winds. It can also be coordinated with your wear and floating vest. An advanced comfort function that enhances the fit and concentration in tournament scenes where every second counts. ■ D.D.SYSTEM (Direct Dial System) — Easy fit with dial operation By operating the dial on the side, you can tighten and release with a single action. When the wind suddenly gets strong, tighten the dial to increase the fit, and loosen it during breaks to relax. It has a wide adjustment range, and can be adjusted for people with small head sizes, as well as loosening the head circumference to a king size level. ■ With adjuster ■ Size: Free (F) 58-60cm I am also listing on other sites, so I may delete it suddenly. Thank you very much.
