The back is fully mesh, so it's extremely breathable. It's see-through due to the mesh, so you'll need to wear an undershirt. There is some wear and tear. I don't see any major defects, but since I'm not a professional, I may have missed something. Please understand. Returns and claims are not accepted, so please contact me if you have any concerns. It's been folded and stored. There may be storage wrinkles that weren't in the pictures due to the passage of time, so please understand. It will be sent via Nekopos in a simple package with only one vinyl sheet. It may also be listed on other sites. In the event of a discrepancy, please be willing to cancel the order.
