Nicely made.
Size: X-Large, Color: Indigo
This is a nicely made jacket. Several people have commented on how they like the coloration. My only complaint is that it is a bit smaller than advertised. I normally wear XL jackets and shirts, however, this jacket fits very tight. I would recommend getting one size larger than what you normally wear.
