Size... I put 80cm, but it's an M size. Please refer to the 8th image for size. It's the type that can be turned inside out to dry easily. Please refer to the 4th image. The hem is fastened with hook-and-loop fasteners that don't snag. Lint tends to stick to it. Please check the 5th image. It's a size adjustment type at the waist. It is not a belly band.
