The easy to use, safe, high performance, wash-in waterproofing for cotton, polycotton and canvas. Adds Durable Water Repellency; reducing weight gain and maintaining the breathability of cotton, polycotton and canvas, in wet weather.

How Nikwax Cotton Proof™ protects

Nikwax Cotton Proof™ has been specifically designed and optimised for breathable cotton, polycotton and canvas materials; it leaves a flexible water repellent treatment on individual fibres allowing moisture vapour to pass through, maintaining breathability, prolonging the life of gear and optimising performance in wet weather.

Nikwax Cotton Proof™ is easy and quick to apply in a washing machine and ensures that the treatment goes right through the garment. The highly Durable Water Repellency (DWR) of Nikwax Cotton Proof™ develops on air drying. Therefore the need for tumble drying is removed, saving energy.
