We ordered a limited supply of medium t-shirts believing that there would be little interest. Turns out, we were wrong.  DiamondCentric will re-stock shortly but as for now, we are momentarily out of stock on that item and will need at least two weeks to refill. If you are interested in this size, please contact me at TwinsFanc1981 [at] Gmail [dot] com. 

Sorry for the inconvenience!
