This is a Carhartt Sierra Jacket. It's a combination of the Detroit Jacket and the Active Jacket, and it looks really cool. The lining is made of boa material, which is very warm. The size tag is missing, so I'm not sure of the exact size, but it feels like a size M, and I think it's a size that anyone can wear and look good in. The color is dark brown, which is a very cool color. It's gradually gaining popularity and the price is going up, so if you're looking for one, get it soon. Color: Brown系 (Brown-based)
