Marmot DWR Technologies

Durable Water Repellency. The durable water-repellent finish increases the surface tension on the face fabric of your garment allowing water droplets bead up and roll off. While not able to withstand much water pressure it will help keep the shell fabric from saturating and reduce the internal condensation. Keeping you drier and warmer.

The test for water repellency is called the Spray Test. Results are given by the % of the fabric still beading up after spraying water on the fabric after washing. For example: 80/20, this means; 80 points (or %) after 20 washing. 80/20 is the standard for high level DWR. Enduro DWR is a special formulation which increases the durability to 80/100. The higher the points and the more washings the better.

To maintain highest DWR performance we recommend washing with low surfactant and easily rinsed cleaning products. High surfactant detergents can leave residues which breakdown the surface tension of water and defeats the effectiveness of any DWR finish. DO NOT use fabric softeners.
Grangers make excellent products for the care of outdoor products.

Enduro DWR
This specially formulated DWR will maintain its effectiveness for up to 100 washings. Enduro DWR water repellent finish is pressed into the fibers of all MemBrain™ shell fabrics not just on the surface. And with our unique resin and a double application process it will work better in the field, last even longer and reduce condensation better.
