Retina® is the group name for our Polyamide backpack fabrics that fulfil our strict requirements for sustainability and quality.

Polyamide (Nylon) is a synthetic fiber creating extraordinarily strong and versatile fabrics with high abrasion resistance, very good resilience to wear and tear, and a high breaking extension. Retina® fabrics are based on polyamides but geared toward use in backpacks, which places different requirements on the fabrics. As opposed to fabrics made for apparel, the focus here is heavy wear and strength. Breathability is of less importance, so we often use a PU coating or a TPU laminate on the inside as wall.

The polyamides we use are derived from recycled, bio-feedstock and virgin sources. Please see ‘Polyamide’ for more info about the different choices regarding the origin of our Retina® fabrics.

Hardur® is our Aramid (Kevlar® fibers) reinforced fabric. In our stretch Hardur® the Aramide (Kevlar® fibers), an extra strong version of Polyamide, are woven together with elastic fibers, which results in an exceptionally durable fabric, with exceptional stretch and softness.

Aramide (Kevlar® fibers) is made from para-aramid fibers. Since invented in 1965, these fibers have been used in a wide range of functions and applications. Aramid fibers remains unsurpassed for ensuring durability as well as functionality in garments and apparel exposed to high amounts of wear and abrasion. Typical applications are cuffs, knee pads and backpack bottoms.

Regular Hardur® fiber is used for fixed shape wear protection, and Stretch Hardur® fiber for pants, jackets and other equipment, where it offers protection without impeding movement or flexibility.

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.
