Cotton Proof

Description

Nikwax Cotton Proof is a wash-in waterproofing for cotton, polycotton and canvas that restores durable water repellency while keeping fabric soft, breathable and comfortable. Perfect for bush shirts, polycotton hiking pants and canvas workwear, it sheds rain and spray so cotton absorbs less water, dries faster and stays lighter on the move. The water-based formula is PFC-free, solvent-free and non-flammable, making it an easy at-home upgrade for performance and longevity.

Use in a washing machine or by hand after a thorough clean for best results. Cotton Proof bonds to the fibres during a normal wash cycle, so there is no stiff, waxy feel and no heat cure required. Treated garments bead water and continue to breathe, helping regulate comfort during active use in cool, damp or changeable conditions. Ideal for regular maintenance of cotton and polycotton apparel used for hiking, travel and everyday wear.
