Microfiber Laundry Bag

When we machine wash clothes made of synthetic materials like nylon and polyester, our laundry sheds microplastic fibers. You can use an in-drum solution like the GUPPYFRIEND washing bag to reduce microfiber shedding from laundry and prevent microplastics from entering our waterways. The bag was tested over a period of three years by representatives of the outdoor and textile industry, retailers, universities, and the following scientific and independent institutes: German Textile Research Center North-West, DTNW Fraunhofer Institute for Environmental Safety and Energy Technology (UMSICHT) UC Santa Barbara as part of the Patagonia research program The results: The GUPPYFRIEND bag drastically reduced the number of fibers that broke off in the wash. Tests by the Fraunhofer Institute UMSICHT showed on average 79% with partly synthetic clothes and 86% with completely synthetic clothing. The plastic fibers that did break off in the wash were retained in the bag by over 90% in all tests,
