Levitend® are our Polyamide based apparel fabrics. Depending on the intended use, Levitend® can include a mix of other fibers, such as polyester and Elastane. Our goal is to make Levitend® fabrics in full compliance with our strict requirements for sustainability and quality.

Polyamide (Nylon) is a synthetic fiber that creates extraordinarily strong and versatile fabrics with high abrasion resistance, very good resilience to wear and tear, and a high breaking extension.

The Polyamides we use are derived from recycled, bio-feedstock and virgin sources. Please see ‘Polyamide’ for more information about the different choices regarding the origin of Levitend®.

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.

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.
