Cutan® is a proprietary Klättermusen waterproof and ventilating technology developed to improve on existing fabrics both in performance as well as sustainability by developing PTFE-free membranes to become fluorocarbon-free in production. Cutan® fabrics are soft, flexible, have great stretch and are fluorocarbon-free. 

Cutan® Super Stretch consists of three layers: an inside layer in polyamide, a waterproof polyurethane membrane in the middle and an outer fabric of polyamide and stretch fiber. The three fabric layers are laminated together into one single fabric. 

Cutan® Stretch RP consists of three layers; an inside fabric in polyester, a waterproof polyester membrane in the middle and an outer fabric of 100% Recycled Polyester (RP). The three fabric layers are laminated together into one single fabric. Cutan® Stretch RP is 100% recyclable.

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.
