Navy long-sleeved rash guard. Width: Approximately 49cm Length: Approximately 61cm - Color: Navy - Size: M - Design: Long sleeves, white stripes on the sides - Intended use: Rash guard for marine sports There is a black stain on the underside of the right arm. It's likely oil from marine sports (no stickiness), but it didn't come off (see photo 6). There was a mark on the chest and just above the text on the back, but it has come off cleanly. There is no fading or tearing, so I think it can still be used. Thank you for looking.
