THIS is a nice, CLASSY, dark, gray sport coat, almost one shade shy of almost black.  It is a sport coat and definitely--as advertised--a slim fit.  It is best used in a fairly dressed-up situation.  You might get away with a nice polo/golf shirt under this, but it is close..  All in all, it is a versatile, nicely made sports jacket with lots of potential uses.  I really like it.
