Palm FX PFD
Dry tops and dry suits as well as other “dry” kit are treated with a DWR finish. DWR stands for Durable Water Repellency. This is the treatment that makes water form as droplets or beads on your kit. When this starts to wear off (which it will) your kit will start to soak up the water. This may not make it through the laminated layers of the fabric but it will comprimise the breathability and effectiveness of your kit. This is known as “wetting out”.
