Simple and stylish black leather double rider's jacket. - Color: Black - Material: Leather - Style: Double Rider's - Pockets: Zippered pockets - Design: Simple and stylish - Collar: Stand collar It's a simple double, not studded. When you zip it all the way up, it can be worn like a single rider's jacket. Approximate measurements (flat lay): Shoulder width: 47 cm Body width: 56 cm Waist width: 51 cm Length: 65 cm Sleeve length: 65 cm Please refer to the photos. When I was 180cm tall, weighed 70kg, with a chest of 100cm and a waist of 77cm, it fit perfectly with a sweatshirt and a denim jacket underneath, zipped up. However, now I weigh 80kg, with a chest of 105cm and a waist of 88cm, it became tight when wearing a denim jacket over a sweatshirt. I can only wear it unzipped. Although it's supple leather, due to its thickness, some people find rider's jackets cold in midwinter, but you can wear it even in midwinter by layering. It has a similar leather thickness to Schott rider's jackets, but it's not as stiff, and is slightly more supple and easier to wear. Perfect for those who don't like the bulkiness of down jackets. You can wear it more like a musician than a rider! Thank you for looking.
