When you notice your waterproof/breathable jackets and pants starting to soak up water, it's time for this stuff. TX-Direct will make water bead again plus rejuvinate the breathable membrane's capabilities. The wash-in product is great because it coats every part of your garment, and air drying afterwards is all that is necessary so you can protect older garments from heat. Using 100ml per garment and a max of 2 garments in your machine, add TX-Direct into your detergent dispenser and run the synthetic cycle with slow spin.
