But these synthetic fabrics, from which 60% of all clothing on earth is made, have a big hidden problem: when they’re washed, they release tiny plastic bits -- called microfibers -- that flow down our drains, through water treatment plants, and out into our rivers, lakes and oceans by the billions. That is why we have chosen to make our new race shirt out of wool, it is biodegreadable, in high quality and you can wear it for all purposes. It does not smell and you don´t have to wash it after every use.
THE PROBLEM WITH YOUR RUNNING CLOTHES
Most of us wear synthetic fabrics. All increasingly made of synthetic materials -- plastic, in fact. And each year, all over the world - millions of race shirts are printed - in synthetic materials.
