Fluorinated DWR (durable water repellent) finishes help keep garments dry but contain environmentally harmful components.
Our durable water repellent (DWR) finish is a coating added to the fabric of our waterproof/weatherproof garments, which helps moisture bead up and roll off the outer fabric; this prevents soaking from the outside and the user becoming cold, clammy or wet, which could be life-threatening in extreme conditions.
Fluorinated DWR finish is a functional chemical coating containing PFCs (short for perfluorocarbons), that the outdoor industry has long relied on to make garments water-resistant. But, they’re nonbiodegradable chemicals with an environmental cost. PFCs are extremely effective at repelling water, but because of their impact, we’re in the process of eliminating them completely from the clothing we make.
We are converting noncritical products with a DWR finish (around 90 % of our weather/waterproof garments) to become PFC free by Fall 2022, including items like insulation pieces, midlayers and some outerwear. For critical DWR applications, like a rain jacket you’d wear for 24 hours, we do not yet have a DWR solution that meets the functional needs of these garments. The brightest chemists are helping us to find a solution for this remaining 10% of our products.
