Nikwax SoftShell Proof Wash-In

Nikwax SoftShell Proof™ Wash-In is a high-performance waterproofing solution formulated to enhance the water repellency and breathability of softshell garments. Easy to use in a washing machine, this non-flammable, PFC-free treatment revitalizes softshells by adding Durable Water Repellency (DWR) to the fabric without requiring heat drying, saving energy and preserving garment longevity. It’s specially designed for use with popular softshell brands, restoring their performance to keep you warmer and drier in damp conditions.

Softshells, known for their breathability, stretch, and weather resistance, can lose up to 70% of their breathability if the fabric begins absorbing water. Nikwax SoftShell Proof™ maintains the balance of breathability and water repellency by creating a flexible, water-repellent barrier on each fiber. This ensures moisture vapor can still escape while keeping rain and wind out, allowing you to stay comfortable in a wide range of conditions.

For best results, clean your garment with Nikwax Tech Wash® before waterproofing. Once treated, the DWR will develop as it air dries, enhancing comfort without needing a tumble dryer. Unlike many solvent-based aerosols, Nikwax SoftShell Proof™ is eco-friendly and does not require heat, so it’s safer for both the environment and your clothing.

Choose Nikwax SoftShell Proof™ Wash-In to extend the life and enhance the performance of your softshell clothing, ensuring optimal protection against wind, rain, and cold while maintaining comfort and breathability.
