I'm pretty sure this was just a normal t-shirt till its latest X-Gene kicked in...and then it became the 100% polyester X-Men Logo Black Polymesh T-Shirt! Now an official member of Professor X's motley band, the X-Men Logo Black Polymesh T-Shirt goes on all sorts of adventures. I once saw it defeat a Sentinel while thumbwrestling Sabertooth while folding its laundry! That's right, polymesh shirts have their own laundry! It's a mad, mad world and the only thing that makes sense is this breathable mesh shirt.
