Out of the wrapper they fit fine.  Shrank over 3 inches in length and 4 inches in girth not to mention neck size and sleeve length during first wash.  If you want a medium size "t", order the large tall and wash it.  As a side note, the seller has a very distorted view of the color "moss green".  What you will get is a very dark olive drab/brown.  As of this review, the seller has not corrected the color issue in the product description.
