Simple black long-sleeved undershirt made of breathable mesh material. - Color: Black - Sleeve Length: Long Sleeve - Features: Mesh material present - Design: Simple design - Back Design: Solid color back Thank you for viewing. I'm selling this because it's been outgrown without being worn much. I think the condition is good, but it's been stored at home and judged by a layman, so I would appreciate it if you could understand. The back and armpit areas are made of mesh material, which seems cool. Thank you.
