I bought this one for my BF as a surprise and he immediately loved it.  He's 6'3" and slim so I bought the XL (this is his normal tshirt size.)  It fit perfectly because he's a thin guy, but he knew if it shrank even a little it would be too tight.  He also thought the collar was too a little too tight.  I returned it and I'm waiting for the XXL to be in stock.  I would recommend everyone order a size up from what you normally get.  Very comfy shirt and it's the exact one they wear in the episode "The Gang Reignites the Rivalry"
