“Wet out” can happen when liquid saturates your garment’s outer fabric leaving you feeling damp as if your garment is leaking, even when it’s not.
To prevent wet out, all GORE-TEX® outer fabrics are treated with an ultra-thin treatment called DWR, a durable water repellent polymer. DWR penetrates the fibres and lowers the surface tension of the fabric, causing water to bead up and roll off the outer layer of fabric, instead of being absorbed.
DWR is not permanent. Regular wear and tear, exposure to dirt, detergents, insect repellent and other impurities can shorten its lifespan.
If you can no longer reactivate the factory applied treatment apply a new water-repellent treatment to the outer fabric.
