I'm selling this because I haven't had many opportunities to wear it after purchasing it. I've worn it less than 10 times. It uses approximately 1mm thick sheep leather. It's characterized by a slightly stiff raw hide with a substantial thickness. The tanning is chrome tanning, and after dyeing with water-soluble dye, it's finished with pigment, resulting in a uniform and beautiful surface. This allows you to enjoy the appearance of a rigid denim jacket, which is also a design source, and the way it looks after wearing it. This leather jacket is designed with the 1st. G-JACKET as its design source. The cinch back and unique tuck specifications also take into account the ease of movement of workwear at the time, and it's easy to see why it was popular as workwear. By updating the simple design of the time with Schott's specialty leather, it has been finished as a piece that can be enjoyed even more today. Please check the official website for details on sizing and how it fits.
