Nikwax Tech Wash. A thoroughly safe, effective and environmentally friendly way of cleaning all your outdoor clothing. Garments that are cleaned regularly with Tech Wash perform better, FACT! Clean garments breathe better, are lighter & last longer. Normal detergents completely strip the surface water repellency from your garments leaving them wet & heavy with reduced breathability, this is known as wetting out. Tech wash enhances the water repellency so your garments can breathe better & stay lighter. Its not just about performance, you wouldnt wear everyday clothes that had not been washed for months, so why wear dirty clothes doing the activities you love? Think of washing and re-proofing your kit like servicing your car, you (hopefully) wouldnt expect your car to keep going forever without regular servicing, look after your kit & it will look after you.
