Since their founding in 1972, Thermore has been a leader and innovator in thermal insulation. The company manufactures a range of down alternative fibers for the outerwear market. The Ecodown® product line, made exclusively from post-consumer PET water bottles, is their most recent innovation in this space and was launched in 2018.
Ecodown® is a synthetic down alternative made exclusively from post-consumer plastic.
Used PET bottles are repurposed following standard recycling procedures. The PET flakes are melted and spun into new fibers. These fibers are then used to produce Ecodown insulation for outerwear.
Using 100% post-consumer plastic bottles to create Ecodown® is seen as better than using virgin petroleum. According to the company, up to ten bottles are recycled for each jacket insulated with Ecodown fibers.
Ecodown is available in 5 varieties as free fibers as well as rolled fabric in a number of weights and thicknesses. According to the company, Ecodown can be used without quilting or fabric restrictions, can be washed or dry cleaned, and is highly durable. Ecodown traps warmth within air pockets and mimics the insulating effects of down. Compared to traditional down, Ecodown fibers maintain warmth even in damp conditions, do not clump when washed, and are fast drying.
