DWR tech

Durable Water Repellant
DWR (Durable Water Repellent) is a coating that is applied to fabrics which makes them water-resistant, or hydrophobic. It's cute to think of a fabric as being afraid of water. Now if only they could make a bearphobic coating. A DWR finish doesn't interfere with breathability, which makes it perfect for adverse conditions in the backcountry.
