10 Best Waterproof Spray For Clothing 2025 in the United States

The Nikwax Hardshell Cleaning & Waterproofing DUO-Pack offers a convenient solution for cleaning and waterproofing technical outerwear and other waterproof clothing. This product includes two 300ml bottles: the Tech Wash and the TX.Direct Wash-In. The Tech Wash safely cleans technical synthetic outerwear without damaging the existing waterproofing treatment, while the TX.Direct Wash-In restores and enhances water repellency and breathability. This makes it ideal for maintaining rain and ski jackets, waterproof fabrics, and other technical clothing from brands like Patagonia, North Face, and GORE-TEX, among others.

One notable advantage of this product is its easy application method; both solutions are designed to be used in a washing machine, which simplifies the process of cleaning and re-waterproofing your gear. Additionally, the product is environmentally friendly, being PFAS-free, biodegradable, and water-based, which reduces its impact on the environment. Users should be aware that the items must be cleaned with the Tech Wash before applying the TX.Direct Wash-In, which might add an extra step to the maintenance process.

Also, because it's a wash-in solution, it may not be suitable for items that cannot be machine-washed. Given its features and environmental considerations, this product is a strong choice for those looking to maintain and extend the life of their waterproof clothing, especially for outdoor enthusiasts who rely on high-performance gear.

The GEAR AID Revivex Durable Water Repellent (DWR) Spray is designed to restore and enhance the water repellency of a variety of waterproof-breathable fabrics, including GORE-TEX jackets, nylon tent flies, and down jackets. One of its notable strengths is its ability to maintain the breathability of the fabrics it treats, making it suitable for high-performance outdoor gear.

The product is available in a substantial 16.9 oz bottle, which can treat up to 6 jackets, making it a cost-effective solution for frequent outdoor enthusiasts. The non-aerosol trigger spray design ensures easy and even application, ensuring that every drop is used efficiently. Additionally, the spray is PFAS-free and contains zero fluorocarbons, making it a more environmentally friendly option compared to other waterproof sprays on the market.

However, it requires the use of Revivex Pro Cleaner before application to achieve the best results, which could be seen as an extra step for some users. While it performs well across various fabrics, its effectiveness on materials other than those listed may vary. The product is well-regarded in the outdoor community, as indicated by its high ranking in the Sports & Outdoors category. It is a good choice for those looking to maintain the performance and extend the life of their outdoor gear, though users should be prepared for the additional cleaning step for optimal results.

The Fabric Waterproof Spray by Better Boat offers a comprehensive solution for waterproofing a variety of materials, including outdoor marine canvas, boat tops, vinyl seats, tents, clothing, boots, and jackets. One of its major strengths is its strong water repellency, as it effectively beads water off and wicks it away from the fabric and vinyl surfaces. The spray creates a breathable water barrier, which is crucial for maintaining comfort in garments and other materials.

Its water-based formula is also a positive feature, as it avoids the fabric erosion that can occur with solvent-based formulas and is non-hazardous, making it suitable for indoor and outdoor use. This spray is versatile and compatible with a wide range of fabrics, including canvas, vinyl, and upholstery, which makes it ideal for multiple applications like bimini tops, boat covers, and outdoor cushions. Additionally, being made in the USA with a PCA-free and low VOC formula is commendable, addressing environmental concerns and assuring premium quality.

The product's durability can be questioned as it might require reapplication after exposure to harsh conditions or over extended periods. The application method is straightforward but might be time-consuming for larger areas. This spray would be especially beneficial for those frequently exposed to outdoor elements, like boat owners and campers, seeking a reliable waterproofing solution that does not compromise fabric integrity.
