Nikwax Cotton Proof Wash-In Waterproofer 300ml Surplus a quick-release buckle for easyNikwax Cotton Proof is an easy to use wash in waterproofer that adds water repellency to your cotton, polycotton and canvas clothing and equipment. Cotton based fabrics are breathable but are also highly absorbent and retain water which makes them heavy and restricts their breathability. To prevent this you can use Cotton Proof to add durable water repellency (DWR) to prevent the fabric from absorbing water and allowing water to simply bead off.
