The front part and the three patch pockets are made of solid and heavy denim of Japanese origin in this vest. The back part is made of dark blue cotton fabric. As with a classic pair of jeans, the buttons on this vest are metal. An attached bar with metal buckle in the back allows for moderate width adjustment.Raw Denim. Künzelsau in Hohenlohe was once a jeans stronghold until a major player in the industry ceased production there. Four friends, Christian Hampel, Guido Wetzels, Peter Bättig and Gerd Walz, decided to take up this tradition when they founded Blaumann in 2013. While others chase short-lived trends, their corporate objective is: producing durable goods. All four of them have experience in the industry. In 20 years, they had more than enough time to learn about possible pitfalls and pick up on the key to success. What they aim for is nothing less than producing jeans in Germany the way they were made in the very beginning – while their credo is: Jeans have to fit casually. Ergo, good cutting is essential. Their denim comes from Japan – it is the best (and most expensive) on the market. They have the solid, heavy-weighted fabric sewn with special felled seams and riveted by hand in stressed areas, thus, making Blaumann jeans almost indestructible. All yarns, buttons and leather labels come from Germany. Only twelve pairs of trousers leave the manufacture every day, each one stamped with a serial number. It goes without saying that trousers made from such raw denim, which has not been pre-washed, by the way, provide a fitting one has to work out first. In return, one can enjoy how they develop into a personal item of clothing by one’s daily movements, wear and tear.Hint:The garment may rub off onto light-coloured materials such as other garments, furniture and upholstery fabrics.General product information Men denim vest, Blue | Manufactum
