PET (also abbreviated PETE) is short for polyethylene terephthalate, the chemical name for polyester. PET is a clear, strong, and lightweight plastic that is widely used for packaging foods and beverages, especially convenience-sized soft drinks, juices and water. Virtually all single-serving and 2-liter bottles of carbonated soft drinks and water sold in the U.S. are made from PET.

At Nau, after collecting waste PET bottles by color, we make sustainable products with recycled polyester fabrics and fillers produced through washing, melting, and spinning processes.

Recycled polyester is a material that can directly counteract the plastic waste issue that is currently problematic. On average, one recycled polyester T-shirt is made from 15 500ml PET bottles.


With the recent rise of animal welfare issues in the fashion production process, artificial fiber fillers are being suggested as an alternative to animal fillers. Instead of using down and goose down, which is not produced ethically, we can use a filler made of polyester (which is a synthetic fiber) and help minimize the production of unethical down.

However, the use of such synthetic fibers is not necessarily good because it increases dependence on fossil fuels.

That's why Nau goes one step further and uses fillers developed from recycled polyester. This filler, reflecting the sustainability of Nau, was applied to the product in a fabric type and a ball-type depending on the application. Like regular synthetic fiber filling, it is lightweight and warm, which protects both animals and the environment.


  • Needs 59% less energy than virgin polyester
  • Reduces CO2 emissions by 32%
  • Keeps non-biodegradable plastic out of our oceans and landfills
  • GRS & RCS certified




We gathered a lot of information on this subject, and there is plenty more to say. Our research began with The Wrap Recycling Action Program (WRAP). WRAP is a national public awareness and outreach initiative designed to make plastic film – including wraps, bags, and flexible packaging – a commonly recycled material with a strong and ever-growing recycling rate.

  • I just received my recycled polyester Randy Goat Lite Zip and Lite Trench and I am in love! These fabulous pieces join my modest collection of Nau items which are not only beautifully made but most importantly made using recycled materials which supports my values as a consumer and CEO.
