Cotton Proof adds durable water repellency to cotton and canvas gear

What Our Gearhead® Experts Are Saying:


"I use Cotton Proof on canvas jackets, old anoraks, and even a few cotton packs—it brings them back to life. Once treated, they stop soaking up moisture, feel lighter in wet weather, and stay far more breathable. It’s an easy wash-in process with a huge payoff, especially if you rely on rugged cotton layers for work or outdoor travel."


With a single cycle in the washing machine, NikWax Cotton Proof extends the life of your canvas shoes, khaki pants, and cotton bags by protecting them from damp-induced rotting.


This wash-in treatment applies an even, long-lasting repellency throughout the fibers, reducing water uptake and helping garments stay breathable during active use. It keeps cotton layers lighter, drier, and far more efficient in changing conditions. Whether we're waterproofing a hardworking field jacket, preparing a canvas pack for travel, or maintaining polycotton outdoor gear, Cotton Proof helps classic materials perform better in modern environments.
