Thank you for viewing! This is an A Bathing Ape long-sleeved shirt. The material is mesh, so it's thin as you can see in the photos (your skin won't be visible). It's incredibly breathable! It has a loose, oversized fit. Feel free to comment if you have any questions! There's a slight yellowing on the inner tag at the neck, but I think it can be removed with bleach. I'd like to include an authenticity guarantee, but it's not available, so please understand. Shoulder width / Body width / Sleeve length / Length Shoulder width: 50cm Body width: 55cm Sleeve length: 61cm Length: 69cm Color: Green系 (Green-based) Stains/tears/smells: Yes
