Why cotton is such a commonly used material...
Cotton is a natural fiber; as such, it is renewable, biodegradable and can be produced organically. It is highly versatile and can be used to produce many fabrics, each with different properties. Additionally, cotton can be blended with synthetic fibers, such as polyester, to combine the desirable properties of both materials.

Cotton fabrics are breathable, absorbent and strong. They are used in the manufacture of clothing and outdoor equipment, but are not inherently water repellent.

Once cotton gets wet, it stays wet…
Cotton is highly absorbent and retains water, so it takes a long time to dry once wet. Therefore, it is important to ensure that cotton outer garments and equipment don’t absorb water, as this will cause them to increase in weight and will impair their breathability.

To prevent cotton fabrics from absorbing water Durable Water Repellency (DWR) can be added by applying Nikwax Cotton Proof.

Cotton outerwear and equipment are ideal for people who need hardwearing items…
Nikwax Cotton Proof is a must have for people who enjoy outdoor pursuits. Whether you have a fisherman’s smock, a cotton or polycotton jacket or a canvas tent, it will provide Durable Water Repellency (DWR) to prevent water absorption and weight gain.

Use Nikwax Cotton Proof™ when your cotton items soak up water...
Your cotton items could be soaking up water just because they are dirty. First, try cleaning them with Nikwax Tech Wash®, and if they are fairly new, or recently re-waterproofed, the Durable Water Repellency (DWR) will be revitalised just from cleaning. But once items have been thoroughly used, you will need to add DWR using Nikwax Cotton Proof, after cleaning first with Nikwax Tech Wash®.

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.
