The Quai de Valmys are nice, theyre a couple grand retail I think. However, that jacket is unlined (as in you have raw leather exposed throughout that jacket) and hit sales everywhere. The leather quality is nice (I would not say Hermes level), but I get less impressed about that kind of stuff.
I just purchased my first leather jacket today. I got it from United Arrows (Japanese Brand). It's made out of sheep, so its pretty soft and lightweight, which I like for this time of year. I went for a medium size, since I liked my clothing fitted. Usually it goes for 80,000yen but it was on sale for 50% off. Here are a couple pictures. I'm wearing some new Diesel jeans and shirt in the last picture as well.
