We scour the globe to find the best fabrics to meet our expectations of quality and comfort for our S4 jackets. Whether Italian wool, stretch-cotton or high-tech polyester, the fabric used for S4 jackets are a synonym for intelligent allure. They confidently defy the weather, range from water-repellent to waterproof and are breathable – and all without PFCs. The highest-quality padding and certified down fillings warm the most demanding of men in the winter, and the ultra-light, stretch summer fabrics clothe that self-same demanding man in summer. This makes our fabric selection unrivalled when it comes to quality and functionality: completely without pretension without compromise.
