Every time we do our laundry, microplastics are released into the water and flushed into our oceans. Synthetic materials, such as polyester, are the worst. The problem is they’re also the best materials to exercise in. And to make matters worse, you need to wash your exercise clothes after every use to avoid infections.

This gym bag is made of Polyamide 6.6, a new material that filters microplastics from water. And it doubles as a washing bag. This means Adidas customers can wash their exercise clothes after every workout without adding to the huge amounts of plastic released into the oceans.
