Designed to return to<br/>materials found in nature.<br/>

By returning to materials found in nature,
PrimaLoft® Bio™ helps to reduce the long-term impact of microplastics in our oceans, landfills and waterways.

Many of our favorite products - from jackets to bedding to wipes - are made from materials that can shed microfibers. No matter how high quality the product, this can occur during washing, normal wear-and-tear and eventual end of life. These products and microfibers often end up polluting environments like our waterways, oceans and landfills. Products made with PrimaLoft® Bio™ fibers have been specifically developed to return to materials found in nature, in an effort to reduce the environmental impact of microfibers and garments throughout their life.

New sustainability.
Same premium performance.

PrimaLoft® Bio™ brings a new approach to sustainability without compromising our industry-leading performance and comfort throughout the life cycle of the garment. This innovation lies within the makeup of the fibers.

PrimaLoft® Bio™ represents a holistic solution for every step of a product’s continued journey.

How does it work?

Biodegradable* fibers.

Appetizing fibers.
PrimaLoft® Bio™ fibers break down at a highly-accelerated rate in landfills, oceans and wastewater because we’ve optimized them to be more appetizing to the naturally-occurring microbes in these specific environments.

Left behind.
These microbes enable synthetic insulation and fabric to return to materials found in nature, leaving behind components like water, CO2, methane, biomass and humus – a common, natural component of potting soil.

*93.8% biodegradation in 646 days under ASTM D5511 conditions (accelerated landfill environment); 76.6% biodegradation in 973 days under ASTM D6691 conditions (accelerated marine/ocean environment); 17.8% biodegradation in 241 days under ASTM D5210 conditions (wastewater environment). The stated rate and extent of degradation do not mean that the product will continue to degrade.
