Restoring Water Repellency

Restoring Water Repellency

"Wet out" can put a real damper on your day. That's when liquid saturates your garment's outer fabric, leaving you feeling damp and clammy - as if your garment were leaking, even when it's not.

To prevent wet out, all WINDSTOPPER® shell fabrics are treated with an ultra-thin treatment called DWR, a durable water repellent polymer that is applied to the outermost fabric layer. DWR penetrates the fibers 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, though. Regular wear and tear, plus exposure to dirt, detergents, insect repellent, and other impurities can shorten its lifespan. The good news is that restoring the water repellency of your WINDSTOPPER® shell is extremely easy.

How to Restore Water Repellency

WINDSTOPPER® outerwear:
Just wash it, rinse it, and put it in the dryer, being sure to follow the manufacturer's instructions. The washing removes 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 following the manufacturer's instructions. This typically involves applying a topical treatment available at most outdoor retail shops. We do not recommend wash-in treatments as they can interfere with breathability.
