Lovar

Oculus® is the group name for our polyester apparel fabrics, produced in accordance with our strict requirements for sustainability and quality. These fabrics can include a mix of polyester or Elastane to get the desired qualities.

Polyester has close to no water absorption, high abrasion resistance, high tensile strength and is very wrinkle resistant. This makes it ideal for use in outdoor packs and apparel.

PrimaLoft® Gold Active+

PrimaLoft® Gold Active+ delivers the breathable warmth necessary to keep you dry, comfortable and regulated - from morning runs to alpine pursuits. PrimaLoft® Gold Active+ is a thermally efficient insulation that provides just the right amount of warmth, breathability and bidirectional stretch to keep you moving fast and free. The fabric can trap the excess moisture vapor that builds up during highly intense activities.

Combine exceptional breathability, 4-way stretch and recovery, water resistant thermal efficiency and 55% post-consumer recycled fibres in PrimaLoft® Gold Insulation Active+ and you have a garment that will withstand any activity and any weather.

PrimaLoft® Bio

Most products we use are made from materials that shed microfibers during washing and wear and. These microfibers are harmful and may pollute our oceans, landfills and waterways. PrimaLoft® Bio fibers were developed to return to the materials found in nature, in an effort to reduce the environmental impact of microfibers and garments throughout their life. Same great performance, but with a new holistic solution of the journey of a garment.

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.
