WindStretch™ is a softshell fabric with outstanding abrasion resistance and stretch to allow big movements. Well-suited for high-intensity activities the material also is ventilating, moisture wicking and dries quickly. WindStretch™ has very good wind resistance and we use it in softshell products where flexibility and durability are important. WindStrech™ will retain its visual appearance even after heavy use without losing color or pilling.

WindStretch™ fabrics are bluesign® approved.

WindStretch™ 180 g/m2 is versatile soft-shell with excellent durability and stretch. The fabric is a blend of 70% recycled polyamide, 20% polyester and 10% elastane with a fluorocarbon-free water repellent.

Light WindStretch™ 159 g/m2 is our lightest, fast-drying and most stretchy softshell fabric. It is a blend of 85% recycled polyamide and 15% elastane with a fluorocarbon-free water repellent.

Polyamide is a durable and strong fiber, increasing the life time of the products containing it. The Ultramid® Biomass Balance Polyamide has the same high-quality features as conventional polyamide, but is far more sustainable. In production of Ultramid® Biomass Balance Polyamide a certain amount of fossil resources is replaced with an equivalent amount of renewable feedstock, such as biogas or bio-naphtha. Klättermusen invests in nothing but 100% renewable feedstock. This is a step towards a more sustainable product, contributing to lower greenhouse gas emissions and saving of fossil resources. The amount of renewable resources used is monitored by a third-party certification system. 

We are the first outdoor brand to apply this fiber in our production and hope to inspire others to become more aware of the choices they make.

Durable water repellent - commonly referred to as DWR, is a treatment which creates a water repellent (hydrophobic) surface on a fabric. The water repellent prevents the fabric from becoming saturated with water which both affects the function of the garment and the user experience.

All types of DWR become less effective over time, because of wear, washing and ultra-violet radiation from the sun. This degradation over time requires re-proofing the fabrics which can be performed at home using wash-in or spray-on DWR.

Klättermusen uses DWRs 100% free of fluorocarbons. We were the first outdoor company to completely remove PFOA (one of the most hazardous fluorocarbons) from all garments already in 2008.

Fluorocarbons are commonly used because they technically are effective – however, they are also an endocrine disruptor proven to cause reproductive harm. Fluorocarbons present a growing problem in nature and the outdoor industry which professes to care about nature.
