Take a look see at this crazy soft 100% cotton Superman Distressed Super S 30 Single T-Shirt, which is a top quality t-shirt and shows off the classic Superman symbol on a blue t-shirt! '30 Single' denotes a kind of sheer material, mostly described as 'silky'. The Superman Distressed Super S 30 Single T-Shirt is a fancy Superman symbol t-shirt for red letter days. I'm not entirely sure what that means, but you will enjoy this iconic t-shirt!
