Nikwax is the world's leading brand of safe, high performance waterproofing, cleaning and conditioning products for outdoor gear. Their products prolong the life and enhance the performance of clothing, footwear and equipment.
Most waterproof outdoor clothing, footwear and gear has a special coating of Durable Water Repellent (DWR) which causes water to bead up on the surface. When functioning correctly, it prevents water from entering while allowing moisture vapour (sweat) to escape. When dirt and other contaminants degrade the DWR, the material can start to soak up water, reducing breathability and causing it to 'wet out'. Regularly cleaning and waterproofing is vital to ensure you get years of use from your outdoor gear.
