DWR: Durable Water Repellancy

The DWR is perhaps one of the most important factors of a garments continued breathability and capacity to keep you dry and comfortable. Basically a DWR is a coating that is applied to the outside of the fabric that increases the contact angle or surface tension of the fabric when water comes in contact with it. This causes the water to bead and to simply roll off your garment, instead of allowing it to flatten and seep into the fabric. All jackets are treated with this DWR layer when made, however over time with use it will wear away. Abrasion, oils and dirt will all degrade the DWR, and as such it will need to be re-applied at intervals all determined by how often you use your garment and how well you care for it. Once the DWR has been worn away, the garment will be less breathable and also may “wet out” – a term that basically means that the face fabric will absorb water. This will severely hamper the fabrics ability to transfer away moisture from the jacket.

Even though your garment will still be waterproof, its ability to remove your sweat will be diminished significantly and you may think that the jacket isn’t waterproof anymore, or that it is leaking. What actually is happening is that the water vapour is condensing back into liquid when it hits a wet face fabric.
