Signal Jacket No. 4

The Signal Jacket No. 4 continues the Werkhaus exploration of contrast and modular construction. The body is crafted from supple black leather, while the sleeves are cut from reclaimed sage-green denim from the 1970s, giving the piece a subtle vintage character. The streamlined silhouette is framed by a narrow stand collar and twin metal zips running down the front, creating a strong vertical outline.

Functional details such as the double front zippers, buttoned collar tabs and cuff buttons emphasise the jacket’s utilitarian attitude. A modular central leather panel can be unzipped and removed, allowing you to reduce the width of the jacket by approximately 9–12 cm and fine-tune the fit to your body.

Straight, close-fitting body with stand collar, double zipper front and long sleeves in vintage denim. Width adjustable via removable central leather panel.
