The mesh is made out of monofilaments, which are more like sticks than threads, and thus does not release fibers itself. On rare occasions, depending on the mechanical condition of your washing machine, the binding tape around the bag may release a few fibers. The binding tape’s total surface is 0.05m2 and about 100 times smaller than the textiles inside. A washing bag filled with three fleece jackets has an approximate potential fiber-losing surface of 1,9m2 (inside and outside). We are working on alternatives, but we have accepted this compromise at the moment because it extends the overall lifetime of the bag. We constantly test and improve the overall quality of the bag itself and its washing and stability performance.
