Is there a DWR layer on the most outer fabric surface?
No, this is 3 layer Gore-Tex pro...waterproof and breathable..no DWR necessary.
Yes, there is a DWR (Durable Water Repellent finish) on all Gore-Tex shells. It keeps the face fabric from wetting out, which can decrease breathability. Marmot uses a long lasting fluorine based resin. Machine washing warm with a powdered detergent and then tumble drying medium until completely dry will help maintain the water repellent finsh.
