Just machine wash it, rinse it, and put it in the dryer, being sure to follow the manufacturer’s instructions on the care label inside. The washing removes dirt and other contaminants and the heat from the dryer helps redistribute the DWR treatment on the fabric surface.
If water fails to bead up on the surface of your cleaned and tumble-dried garment, its DWR treatment has reached the end of its useful life. But don’t worry: You can restore the garment’s water repellency by applying a topical water repellency restorative (DWR treatment) for outdoor fabrics, available at your local outdoor retailer. We do not recommend wash-in treatments, as they can hinder your garment's breathability.
We do not recommend the use of waterproofing waxes or greases as they can seriously affect the footwear's breathability. Apply only treatments, polishes, conditioners, and dressings recommended by the manufacturer. Always check the manufacturer’s care instructions on the label of your footwear first.
The GORE® CROSSTECH® fabric in your garment provides waterproof protection without a water-repellent finish, although the garment’s outer shell fabric has been treated so that water beads up on its surface in the rain. This treatment may wear off after use but can be restored by ironing your garment using a warm steam setting after cleaning according to the manufacturer’s instructions. After extended wear, you may need to use a commercially available, non-silicone water-repellent product to treat the outer fabric.
