This is a BILLABONG front-zip design top. I bought it for around 30,000 yen. It was custom-ordered, so the exact size isn't specified, but it was used by an adult male who is 173cm tall and weighs 65kg. It stretches incredibly well. It's still wearable, but I'm selling it because I started using a different brand. * There are no holes, but as you can see in photo 5, there are two areas of damage on the right arm. I don't think it's at a level where water would seep in. This item shows signs of use overall. Please refrain from purchasing if you are sensitive to this. - Brand: BILLABONG - Material: 80% Nylon, 20% Spandex, 100% Neoprene - Design: Front Zip - Color: Black (Gold logo) Outer Fabric...Rubber Lining...Standard Thickness...~3mm Gender...Men's Sleeve...Long Sleeve
