A high-performance waterproofer designed to enhance the performance and revitalise the breathability of softshell garments. It is easy to use in your washing machine, non-flammable, and PFC-free.

Why breathability depends upon water repellency-
Breathable softshell garments are most likely to get sweaty and wet inside when used in damp or wet conditions. If the outer fabric absorbs water, the garment can lose up to 70% of its breathability. Therefore, the Durable Water Repellency (DWR) on the outer fabric of your softshell jacket must be maintained to ensure comfort. It will eventually wear off and need to be renewed with Nikwax SoftShell Proof™.

Softshells provide versatility-
Softshell fabrics combine the desirable properties of hardshells and fleeces to improve user comfort while protecting in most conditions.

Softshells are breathable and stretchy while also being highly water—and wind-repellent. They fit the shape of the wearer, allow the movement of moisture away from the body, shed water, and protect against wind chill. Softshells provide a versatile outer layer that can cope with most conditions.

The durable Water repellency (DWR) coating is essential for maintaining softshell fabrics' water repellency and breathability. Nikwax SoftShell Proof™ has been specifically formulated to maintain the optimum performance of softshell fabrics.

Use Nikwax SoftShell Proof™ when your softshell garment soaks up water-
Your softshell garment could be soaking up water just because it is dirty. First, try cleaning it with Nikwax Tech Wash®, and if it is fairly new, or recently re-waterproofed, the Durable Water Repellency (DWR) will be revitalised just from cleaning. But, once the garment has been thoroughly worn, you will need to add DWR, using Nikwax SoftShell Proof™, after cleaning first with Nikwax Tech Wash®.

Softshell garments need Nikwax SoftShell Proof™ to maintain performance-
Alternative waterproofing products are often solvent-based aerosols; alternatively, they may be water-based and use fluorocarbons. Aerosol products are flammable, and fluorocarbons pose a potential risk to the environment and to the long-term health of the consumer.

Nikwax SoftShell Proof™ is a safe product to use on softshell fabrics. It is Water-Based, non-flammable, and fluorocarbon-free. Nikwax SoftShell Proof™ has been specifically designed and optimised for softshell clothing, providing Durable Water Repellency (DWR) while maintaining breathability. Nikwax SoftShell Proof requires no heat to develop its DWR, so it is not necessary to use a tumble dryer for best results.

Cleaning properly can be as important as waterproofing-
Using the right cleaning product is as important as using the right waterproofing product. Conventional detergents leave behind a thin water-absorbent film on materials, which masks their water-repellency. Therefore, always clean your waterproof garments with Nikwax Tech Wash®. Remember that dirt itself works against water repellency, so regular cleaning will enhance performance.

How Nikwax SoftShell Proof™ Wash-In protects-
Nikwax SoftShell Proof™ Wash-In is easy and quick to apply in a washing machine, and its highly Durable Water Repellency (DWR) develops on air drying. The washing machine application ensures that the treatment goes right through the garment, treating seams, tapes and cords, and the fabric. Also, as the need for tumble drying is removed, this saves energy and protects more vulnerable, older garments from heat. Nikwax SoftShell Proof™ Wash-In has been specifically designed and optimised for softshell garments; it leaves a flexible water-repellent treatment on individual fibres, allowing moisture vapour to pass through, maintaining breathability.
