Coutan® is a proprietary waterproof and breathable technology developed by Klettalmusen, which combines the performance and sustainability of existing fabrics by developing a PTFE-free membrane and eliminating fluorine compounds during production. Developed to improve both sex. Coutan® fabric is flexible, has excellent stretch and is 100% fluorine-free. Constructed of 3 or 2.5 layers of membrane fabric, they are highly waterproof and breathable and are impregnated with a fluorine-free, water-repellent impregnation agent. The membrane is made from polyurethane and is hydrophilic. Coutan® Super Stretch consists of three layers: an inner layer of polyamide, a central waterproof polyurethane membrane and an outer layer of polyamide and stretch fibers. These three layers of fabric are laminated to form one piece of fabric. Coutan® Stretch RP consists of three layers: an inner polyester fabric, a waterproof polyester interlayer, and an outer fabric made from 100% recycled polyester (RP). These three layers of fabric are stacked together to form one piece of fabric. Coutan® Stretch RP is 100% recyclable.

64% Wool, 36% Polyester, 225 g/m²
Wuru® is a blended wool that meets our demands for sustainability and quality. Wool is one of the most versatile fibers and has unique properties. Wool has natural antibacterial properties. This prevents odors from accumulating, keeping you warm in winter and cool in summer. Wool can also absorb nearly a third of its weight in water, making it warm and moisture-wicking even when damp. Wool blends are fabrics of the quality we desire, for example with the addition of polyamide, polyester or TENCEL™. We use wool from a variety of sources, depending on the purpose, placement, and required performance. A wide variety of products are available, including wool.
