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.

Size up! Twice!
Size: XX-Large, Color: Black
Nice jacket, but runs VERY small. I sized up from an XL to a 2XL and it still is snug.
