What is DWR and what does it stand for?
DWR stands for Durable Water Repellent. It is a coating applied to a fabric to make the water bead and roll off the fabric. Durable water repellent treatments are commonly used on the outer fabric of waterproof and breathable garments to prevent the fabric from becoming saturated with water. This saturation, called 'wetting out,' increases condensation on the inside of a garment, reduces its breathability (moisture transport through the breathable membrane) and in some cases lets water through. As the DWR wears off over time, re-treatment is required. We recommend McNett Outerwear Repellent to reapply the DWR on a garment.
