My husband wore this. I think there is some feeling of use, but there are no noticeable stains and it is in relatively clean condition. Size 1 Shoulder width 42.5 Sleeve length 64 Body width 53 Length 82 Quoting the description from the official website. This N-3B JACKET is designed with the SOF (Special Operations Force) in mind, and uses Cordura nylon for the material. Cordura is a registered trademark of Invista, and is a durable fiber with 7 times the strength of nylon. It has water repellency, durability, and high resistance to abrasion, making it extremely robust and providing maximum body protection. It is a high-performance material used in harsh situations where advanced functionality is required. The insulation uses the high-performance material Thinsulate Ex-Soft, achieving lightness and high heat retention comparable to down. Although a voluminous type of Thinsulate is used, CIVILIZED's signature pattern technology, which allows for high mobility, ensures a comfortable fit without feeling constricting. Among these, the action pleats at the elbows not only enhance arm mobility but also add a moderate military feel, serving as a design accent. While it is common to attach the elbow panels from the top, by cutting out the elbow area and attaching it from below, a more understated impression is given. Although both specifications may seem the same, they create a different impression. It is a time-consuming process, involving cutting out the fabric, but it is an important detail to create a design that is natural and has presence without disrupting the overall balance of the design. The ribbed cuffs prevent cold outside air from entering, and by passing your fingers through the thumbholes, they cover the back of your hands and protect them. The inside of the pockets, including the hand-warmer pockets, is made of brushed material to warm cold hands and fingertips. This is a high-performance N-3B jacket finished with durable Cordura and Thinsulate to protect you from the cold outside air, featuring a total of 10 pockets including hand-warmers, thumbholes as glove alternatives, and a full-face mask gimmick that covers the entire upper body. The front zipper is a top-opening zipper from YKK, a world-renowned zipper manufacturer from Japan. A top-opening zipper is a zipper that can be opened without lowering the slider in emergencies or when quick action is required, and it is a high-performance zipper made possible by YKK's advanced technology.
