Built from recycled 2.5-layer Pertex® Revolve fabric with a fluorocarbon-free DWR treatment, the Downpour Eco is a monopolymer waterproof jacket. It uses a polyester outer and membrane, which means that, in addition to being 100% recycled, it also has the potential to be recycled at the end of its life much more easily than waterproof fabrics made from multiple polymer layers.
