I wear a small and this shirt fits perfect without being too tight (I'm 5'11 and 130 lbs.)  The quality is superb and the price is quite fair.  When I purchased this, the price was $20.00.  I have never heard of this company before and I will look at their other products in the future.  For whatever reason, only the "Rosin" color is $20.00 and the other colors are more than $60.00.  I have no idea why there is such a huge markup on these since the manufacturing costs should be the same (unless grey dye is really 10x as much...)  I would not have purchased this if it wasn't for the low price.
