RARE- Legends Boxing Federation Shirt, Sz XXL

This is an odd bit of sports team clothing. The LBF was founded in 2015. I don't know if it's entirely legitimate, but they still have a Facebook page. Web search "the LBF Legends Boxing Federation AG (LBF) is a company incorporated under Swiss law and domiciled in Engelberg (Switzerland)." Ok. Shirt is in excellent condition! Size XXL. Light weight nylon feel, but there no fabric tag. underarm panel is mesh. Chest- 54 inches around Length- 32 inches Sleeve- 7 inches from top shoulder seam.
