Adds Durable Water Repellency, revives breathability and maintains internal wicking properties. Your raingear could be soaking up water just because it is dirty. First, try cleaning it with Nikwax Tech Wash®, and if it is fairly new, or recently re-waterproofed, the Durable Water Repellency (DWR) will be revitalized just from cleaning. But, once the garment has been thoroughly worn, you will need to add DWR, using Nikwax TX.Direct®, after cleaning first with Nikwax Tech Wash®.
