What is DWR?
The waterproof breathable fabric used on waders and jackets helps to keep you comfortable by allowing warm air to escape outwards and breathe through the membrane, while simultaneously keeping water out.  The DWR coating is what makes water bead up and run off. You may have noticed that over time water will bead up less, and instead the outer layer may begin to soak up or saturate with water. This is often referred to as ‘wetting out’, which doesn’t mean the gear is leaking, but instead means the outer layer is saturated and inhibiting the inner membrane from breathing.  When this happens it can leave damp spots of condensation on the users under layers.

In order for air to pass through the outer layer of fabric there can’t be a saturated layer of water on the outer layer, which is where the DWR coating comes into play. If the outer layer is saturated, it essentially voids the ability of the membrane to do its job, and the warm air won’t be able to escape. This will make the user warmer, sweatier, and more likely to get that damp clammy feeling. 

The trick is to maintain the outer layer of fabric by keeping it clean and using a DWR reviver regularly so that water beads up and sheds off.  

We recommend cleaning and reviving the DWR coating on your waders and jackets regularly, usually 1-2 times per year is adequate (of course depending on use). We recommend Revivex by Gearaid as it uses a simple spray on and let dry method. Start by cleaning your waders or jacket with a simple scrub down or with Pro Cleaner, and then spray with Revivex Durable Water Repellent. Let it dry and you’ll be good to go. 

Then go have some happy and comfortable fishing!
