What Is DWR?
To repel water, outerwear must have durable water repellency (DWR) on its surface. DWR treatment is applied to ski pants and jackets by the manufacturer. This protective coating repels water and keeps you dry.
How does DWR Work?
DWR creates a microscopic barrier that allows water to bead and roll off. When this protective coating is exposed to smoke, sweat, dirt, and other residues, the fabric no longer has the ability to stop the water from entering.
Water is actually attracted to dirt, so a dirty jacket can lead to a wet jacket. Regularly washing your technical outwear in a specialized cleaner will remove dirt and grime, and help revive your DWR. Applying heat after the garment has been cleaned will also help improve DWR performance. If your DWR is still not working well, apply an aftermarket water repellent spray.
Revivex Restores and Protects
Restore the performance of GORE-TEX®, eVent®, NeoShell®, and other waterproof-breathable fabrics by using a gentle cleaning formula like Revivex Pro Cleaner or Down Cleaner. Unlike regular laundry soaps, Revivex products do not contain fragrances, optical brighteners or fabric softeners. These additives can make your cotton clothes smell and feel great, but they can clog technical fabrics and hinder the performance of DWR due to the residue they leave behind.
Over time, DWR treatment wears off causing fabrics to “wet out.” This reduces breathability and creates excess condensation, making you damp and cold. So after cleaning gear, re-proof it as needed with Revivex Durable Water Repellent or Wash-In Water Repellent. Doing so will help maintain your DWR and extend the life of outerwear, whether it’s your first or 100th outdoor adventure.
