Breathable, waterproof clothing can become quickly soaked from the inside under damp and wet conditions. When the outer fabric absorbs water, the clothing can lose up to 70% of its breathability. The durable water repellent (DWR) feature of your jacket's outer fabric must be maintained to ensure wearing comfort. Once the effectiveness diminishes, it can be renewed with Nikwax TX.Direct®. Nikwax TX.Direct® Spray-On is easy and quick to apply, and its high-grade durable water repellent (DWR) property forms during air drying. Tumble drying becomes unnecessary, saving energy and protecting delicate, older clothing from heat. Nikwax TX.Direct® Spray-On has been specifically developed and optimized for breathable, waterproof clothing. It leaves a flexible, water-repellent layer on individual fibers, allowing moisture to evaporate while maintaining breathability. The spray treatment allows for targeted application on high-wear areas (e.g., elbows and jacket seams) without compromising the moisture-wicking properties of the inner lining.
