ZIAS LEATHER JACKET】cow leather The shape of the collar, the size of the pockets, the cuffs, the shape of the belt, etc., The minimalist yet subtle attention to detail and the exquisite matching of design balance results in a timeless and immortal model. The leather is domestic steerhide (the skin of a steer castrated within 3 to 6 months of birth and aged for 2 years, so it has few scratches and is durable). It is 1.2~1.5mm thick, but it has a firm feel while maintaining a soft quality. It is fully chrome-tanned, with a fine and supple grain, and is drum-dyed with a lot of oil. The dye is applied twice to penetrate the core (dyeing even the back of the hair). The finish is completely natural, and the surface is felt-buffed to create a smooth, natural luster. Because the oil feel remains, even if it gets a little scratched, the scratches become less noticeable if you rub them with your hand. It fits your body the more you wear it, and although it has weight, it is easy to wear and conforms to your body. Durable high-density satin is used for the lining. It has a total of five pockets, including three pockets on the inside, providing convenience. This item is made with a commitment to MADE IN JAPAN for the leather, sewing, and everything else. The colors are the classic Black and a new Brown, for a total of two colors. 【MADE IN JAPAN】 [material] Cow Leather Lining 100% Polyester [Size] 1 (Length 61.5cm, Width 59cm, Shoulder Width 52.5cm, Sleeve Length 60.5cm)　　　　　　　I have not worn it outside, but I have worn it a few times at home and there are wrinkles on the sleeves from bending my arms and exercising.
