Microfiber Washing Bag


Guppyfriend Washing Bag prevents pesky microfibers from polluting our rivers and ocean. Microfibers are released when garments made of synthetic materials are washed.


100% polyamide (fully recyclable)


50 x 70 cm (approx. 19.7" x 27.6")


  • Fill bag with clothing made of synthetic materials, such as activewear or swimwear
  • Pull zipper closed to shut bag
  • After numerous washes, you will begin to see clumps of microfibers accumulate. Remove clumps and dispose in the trash.

Pro Tip

Use the Guppyfriend Washing Bag along with the Cora Ball as an individual-level solution for microfiber/microplastic shedding.
