Nikwax SoftShell Proof™ Spray-On – High-Performance Waterproofing for Softshell Jackets & Trousers
Recommended by Game Technical Apparel to restore and maintain water repellency and breathability in all softshell garments.
Product Overview
Nikwax SoftShell Proof™ Spray-On is a premium, easy-to-use waterproofer designed specifically for softshell jackets, trousers, and outdoor apparel. It enhances performance, revives breathability, and restores the Durable Water Repellency (DWR) that keeps you comfortable and dry — even in wet and windy British conditions.
This non-flammable, PFC-free, and aerosol-free treatment is simple to apply by hand, ideal for precise reproofing of high-wear areas like seams, elbows, and shoulders.
Perfect for garments made with Windstopper®, Schoeller®, and other technical softshell fabrics used in Game Technical Apparel clothing.
Key Features
-
Restores Durable Water Repellency (DWR): Prevents water from soaking into outer layers.
-
Revives Breathability: Keeps your garment performing effectively by maintaining airflow.
-
Targeted Spray Application: Apply directly to areas that need extra protection, such as elbows, seams, and shoulders.
-
Eco-Friendly Formula: Non-flammable, PFC and aerosol-free, with no harmful chemicals.
-
No Heat Required: Water repellency develops naturally during air drying.
-
Ideal For: Softshell jackets and trousers with wicking linings.
Why Use This Product
Softshell garments are highly versatile, combining the flexibility and breathability of fleece with the weather protection of hardshells. However, over time, their Durable Water Repellency (DWR) wears off, causing the outer fabric to absorb moisture and lose up to 70% of its breathability.
Nikwax SoftShell Proof™ Spray-On restores this vital water-repellent finish while maintaining breathability, ensuring your gear continues to perform and protect you in wet weather.
Your softshell may simply be wetting out because it’s dirty. First, clean it with Nikwax Tech Wash® — this alone may revive the DWR if your garment is still fairly new. For more worn gear, apply Nikwax SoftShell Proof™ Spray-On after cleaning to fully restore its waterproofing performance.
When to Use Wash-In Instead
If your softshell doesn’t have a wicking lining, opt for Nikwax SoftShell Proof™ Wash-In instead. It ensures full coverage through a machine-wash application. However, for softshells with wicking linings, this spray-on version is ideal, as it preserves wicking ability while reproofing the exterior.
How to Use
-
Shake well before use.
-
Clean first: Use Nikwax Tech Wash® to remove dirt and detergent residues.
-
Protect surfaces from overspray.
-
Spray evenly onto a clean, wet garment from about 15cm away.
-
Wait 5 minutes, then remove any excess with a damp cloth.
-
Air dry (or tumble dry on low if care label allows) — no heat required to activate DWR.

How to Use Nikwax SoftShell Proof™ Spray-On
Softshells Provide Versatility
Softshells are designed for comfort, protection, and performance. They are:
-
Breathable and flexible, allowing moisture to escape.
-
Water and wind repellent, shielding against light rain and chill.
-
Durable and comfortable, providing freedom of movement and all-weather reliability.
To maintain these qualities, regular cleaning and reproofing with Nikwax SoftShell Proof™ are essential.
How It Protects
Nikwax SoftShell Proof™ Spray-On applies a flexible, breathable water-repellent layer to each fibre, maintaining airflow and performance.
It targets high-wear zones for maximum protection and prevents damage to delicate inner linings. The treatment develops fully as it air dries, eliminating the need for tumble drying — saving energy and extending garment life.
Care Advice
-
Always clean with Nikwax Tech Wash® before reproofing.
-
Do not use conventional detergents or fabric softeners.
-
Regular cleaning enhances long-term waterproof performance.
