Dirt and other contaminants can interfere with the waterproof coating of your garment, impacting its breathability. Normal household detergents can compromise the waterproof coating.

Use Nikwax Tech Wash Spray-On for synthetic garments with wicking or absorbent liners and Nikwax TX Direct Wash In for synthetic garments with waterproof, breathable fabrics. For down-filled clothing use Nikwax Down Wash Direct.

Eventually the DWR (Durable Water Repellent) finish on your garment will wear off. You will know it’s time to waterproof when water starts to be absorbed and the breathability is affected, making you feel clammy.

Our proofing products add DWR while maintaining breathability, optimising performance in cold and wet conditions. Use Nikwax Down Proof for down filled items, Nikwax Polar Proof for for fleece items, Nikwax Cotton Proof for cotton and polycotton clothing and Nikwax Wax Cotton Proof for wax cotton items.
