How to Test and Maintain Your DWR for Peak Performance
When your waterproof jacket or boots stop shedding water like they used to, it doesn’t always mean it’s time to replace them — it might just be time to restore the Durable Water Repellent (DWR) finish. DWR is a critical part of how waterproof apparel and footwear perform, helping moisture bead up and roll off the surface while allowing breathability to keep you dry and comfortable. Over time, exposure to dirt, oils, and repeated use can wear down this protective layer. However, with the right care, you can easily test and maintain your gear’s DWR to keep it performing at its best. In this guide, we’ll walk you through how to test your DWR, simple steps to maintain it, and the best methods to retreat your gear for long-lasting protection on every adventure.
What is DWR and Why Does It Matter?
Durable Water Repellent (DWR) is a key finishing treatment applied to the outer surface of waterproof apparel and footwear that causes water to bead up and roll off instead of soaking into the fabric. This invisible coating helps waterproof fabrics shed water, acting as the first line of defense against rain and moisture. While the waterproof membrane underneath provides the primary barrier to water, DWR plays a vital role in ensuring breathability by preventing the outer fabric from becoming saturated, which can trap moisture and inhibit airflow. However, regular wear, washing, dirt, and exposure to harsh elements can degrade DWR over time, causing water to absorb into the fabric’s surface rather than bead off. Without proper maintenance, this reduced performance can leave apparel and footwear feeling heavier, colder, and less breathable in wet conditions — making regular DWR care essential to preserving both comfort and protection.
How to Test Your DWR Coating
Testing your DWR is simple and can help determine whether your waterproof apparel or footwear needs maintenance. The easiest method is the water bead test: lightly spray or pour a small amount of water onto the outer surface of your jacket, pants, or boots. If the water beads up and rolls off, your DWR is still effective. However, if the fabric starts to absorb water, appearing darker or damp, it’s a sign that the DWR has worn down and needs reactivation or retreatment. Another way to check is by observing how your gear performs in wet conditions—if you notice your jacket or boots feeling heavy, cold, or failing to repel water as they once did, it’s time for some DWR maintenance. Regular testing helps ensure your waterproof gear continues to perform at its peak.tead of soaking into the fabric.

The Importance of Drying in DWR Maintenance
Proper drying is one of the easiest ways to maintain your gear’s DWR performance. Many DWR treatments are heat-activated, meaning a quick spin in the dryer on low or medium heat can help rejuvenate the water-repellent finish by resetting the treatment on the fabric’s surface. This simple step can often restore water beading without the need for retreatment. For footwear like boots, it’s important to let them dry naturally, away from direct heat sources like radiators, to prevent damage. Always check the care instructions for your specific gear before choosing the drying method to ensure the best results and avoid damaging the waterproof membrane.
How to Properly Retreat Your Gear
Properly retreating your waterproof apparel and footwear is essential to maintain their performance over time. Start by cleaning your gear to remove dirt, oils, and grime that can hinder the DWR (Durable Water Repellent) treatment from adhering properly. Use a gentle, technical cleaner designed for waterproof fabrics to preserve their integrity. Once clean, apply a DWR treatment, either through a wash-in or spray-on product, depending on the type of gear. Wash-in treatments are ideal for garments like jackets and pants, while spray-on treatments are perfect for targeted application on footwear. Follow the product instructions carefully for best results and always ensure that your gear is completely dry before reactivating the DWR with low heat in the dryer (if the care label allows). Regularly retreating your gear helps maintain its ability to repel water, ensuring you stay dry and comfortable in any condition.
Products eVent Recommends for DWR Treatment
To effectively retreat your waterproof apparel and footwear, eVent fabrics recommends using high-quality, industry-leading products designed specifically for outdoor gear. Nikwax TX.Direct is an excellent wash-in treatment for garments, providing a durable water-repellent coating while maintaining the breathability of the fabric. For footwear, Nikwax Waterproofing for Leather and Fabric spray-on treatment works great, offering precise application and effective protection for boots, shoes, and other outdoor footwear.
Maintaining DWR: Best Practices
Maintaining your DWR (Durable Water Repellent) coating is essential for ensuring your waterproof apparel and footwear continue to perform at their best. To extend the life of your DWR, it’s important to clean your gear regularly using a gentle, technical cleaner designed for waterproof fabrics, as dirt and oils can break down the coating. Avoid using regular household detergents or fabric softeners, as they can damage the DWR finish. After washing, always allow your gear to dry thoroughly before reapplying a fresh DWR treatment. If your gear is starting to lose its water-repellent properties, consider reactivating the DWR by using a low heat setting in the dryer (if the care label allows), or applying a spray-on or wash-in treatment to restore water resistance. Regular maintenance, including periodic retreatment, ensures your apparel and footwear remain functional and reliable, keeping you dry and comfortable no matter the weather.
Conclusion
In conclusion, retreating your waterproof apparel and footwear is a simple yet essential process to maintain their performance and extend their lifespan. By regularly cleaning your gear, testing water repellency, and reapplying DWR treatments, you can ensure your gear continues to offer the protection you need in any weather. With the right care, your waterproof outerwear and footwear will continue to deliver unbeatable waterproof, breathable performance, keeping you dry, comfortable, and ready for your next adventure. Remember, a little maintenance goes a long way in keeping your gear performing at its best, season after season.
