This is an AIDENTIFY surf cap. It's perfect for sun protection or for the colder weather we're entering now. I like this brand and have a collection of marine-themed items. The subtle logo is stylish. Unfortunately, the cap doesn't suit me, so I'm reluctantly selling it. Used once for a short time, only in freshwater. This is a rare item, not available online. Purchased for 7500 yen. Size: Medium Navy nylon cap with the AIDENTIFY logo. - Brand: AIDENTIFY - Color: Navy - Material: Nylon Surfing Surf hat Surf cap Thank you for looking.
