I love me some beefy ts so when I saw them on here I decided to pick up a couple in smoke gray color size L.  After a single wash I feel like they lost about 2inches in length.  Not sure whats up with the sizing as I always wear a size L... As others have suggested on here Id advise going 1size up from your normal size.  Im going to order an XL and see if I can get more length that way., btw Im not super tall , about 58 and the L was SHORT!
