Polyamide is a synthetic nylon fiber, produced from crude oil or renewable plant-based oils. It creates an extraordinarily strong and versatile fabric. In turn, recycled polyamide can be derived from both post-industrial or post-consumer feed stock. In our collection we use a mix of both.

For recycled polyamide fibers, post-consumer waste is our first choice, since we want to help recycling on a global scale any way we can. Post-consumer waste used for recycled polyamide includes discarded industrial fishing nets, old carpets and rigid textiles. Reusing oil based raw materials in a responsible manner is in our mind an important step in the right direction.

Recycling polyamide adds another layer of complexity to the production process, but the result is a reliable, long-lasting fabric that can be used for both lightweight and quick-drying, and wind and rain proof fabrics, depending on the thickness. Using material that otherwise would become waste saves both energy and resources.

We were the first outdoor company ever to use recycled polyamide across our entire backpack line in 2009.

At Klättermusen, we use only 800+ fill power goose down of the highest quality as insulation in our down products. Few competitors can match our warmth-to-weight ratio, and our down keeps its shape and insulating properties for decades if taken care of properly. 

All the down we use is RDS- certified (Responsible Down Standard).

RDS-certified means that the entire supply chain is audited, and the welfare of the birds is respected during their entire life cycle. For example, live-plucking and force- feeding of the animals is strictly forbidden and all the down is fully traceable back to the farm.

We have chosen to work with chlorine-free, unbleached down, which means that a few feathers in every down product will be dark. If you encounter a feather visible through the outer fabric, gently squeeze or shake it until the feather has disappeared.

bluesign® is a standard for environmental health and safety in textile manufacturing. The bluesign® organization provides independent auditing of textile mills, closely examining manufacturing processes from raw materials and energy inputs to water and air emissions outputs.

bluesign® helps us to keep control over the supply chain and choose manufacturing partners based on their commitment to safety and environment.

The bluesign® approval on our fabrics means that it complies with the highest standards of consumer safety by using materials and techniques that save resources and minimize environmental impact. Klättermusen has been a bluesign® system partner since 2007.

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.
