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®.

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.
