Ok, it is true, an Asian XL is a M in the US.. although the fit is a bit snug the pants look pretty cool and they are flexible enough as to be comfy. The construction and materials are very good and the design of the skull is quite a conversation piece at the gym.... I bought the black ones too!!!  I wish they had bigger sizes of all other items advertised at amazon or their webpage... great price for cool looking fashion! My favorite workout shorts to date.
