Fits as I had hoped.  I'm 5'8"/158 lbs and the 4XL fit fine with room to wear a sweater too.  Nice styling and the way the fleece zips into the outer coat you get two additional inside pockets.  The side pockets do not have zippers and could be deeper.  I love that the hood is detachable and when I need it it's deep and fastens securely across my chin to keep the wind out.  We'll see how it wears.  Overall I think it's a great coat for the price.
