The Nikwax TX Direct Wash-in formula is a great way of improving the longevity of your active wear and maximising performance, water resistance and breathability of your technical clothing. Simply wash your products with this water-based fluid in a washing machine or by hand, and air dry to leave your waterproof clothing, bag, or even tent fully water resistant and breathable once more. Nikwax is eco-friendly, biodegradable, non-flammable, non-hazardous, and can be used on waterproof clothing, Gore-Tex®, and eVent® garments.
