Introducing the Guppy Bag

Guppy FAQ

What is the Guppyfriend made of? Is the material recyclable?

Apart from the zipper the bag is entirely made of Polyamide 6.6. The material is untreated, undyed, and does not contain any additives. It’s pure and can even be used in a medical context. Recycled material doesn´t work (yet) for this kind of high-tech mesh. But the washing bag is designed in such a way that it can easily be recycled with identical materials at the end of its lifecycle: The whole bag – except the zipper – is made of a single material.

Do less fibers break when using the Guppyfriend Washing Bag?

Yes. As part of a test program, the Fraunhofer Institute UMSICHT has confirmed that the Guppyfriend washing bag not only reliably retains the breaking microfibers, but also protects the textiles. Compared to washing without the Guppyfriend Washing Bag, on average 86% less fibers break off synthetic textiles.

What kind of textiles belong in the Guppyfriend Washing Bag?

Every textile loses microfibers, but it is the synthetic materials (polyester, acrylic, nylon, etc.) that shed the harmful fibers. Most apparel contains synthetic fibers to some degree (unfortunately, sometimes it is not stated on the label). You can also put pure cotton and wool inside the bag. Textiles from natural materials also lose fibers. The bag reduces fiber breakage, thus protects your garments and reduces wear and tear. You’ll enjoy your clothes for much longer – another sustainability benefit of the Guppfriend Washing Bag.

If you must have stretchy jeans…

It seems to work very well. I’ve only used it with socks, though. They’re the only clothing that really needs nylon and polyester so far as I know.
