Great style chose for any occasion
Size: Medium, Color: Black
Genuinely the perfect fit and great for the style I prefer. Great material and thick to keep you warm but not to hot. Black is deep and adds that depth that I am looking for

Cole Haan hasn't let me down. I have about half a dozen pairs and they are my favorite and most versatile.
