This is a diving hood. It's used, so there may be some discoloration that's difficult to see in the photos, but it's still in good condition and will last a long time for practical use. Please purchase only if you are okay with this. The size is about 56-57cm, but even someone with a 60cm head could wear it, though it would be a bit tight. That's the kind of elasticity and fit it has. It can also be used reversibly. To all the kind divers who are diving refugees during the New Year's holiday, buy this item, drink some Ebisu beer, and imagine the sea while playing in front of the mirror or playing the game of the Seven Lucky Gods. This year will surely be a year of good luck! Viva diving! Hip hip hooray! Diving Scuba diving Scuba diving Marine sports Diving equipment Diving hood
