Nikwax Wool Wash. A thoroughly safe, effective and environmentally friendly way of cleaning Merino wool base layers. Garments that are cleaned regularly with Wool Wash perform better, FACT! Clean garments wick better, breathe better, are lighter & last longer. Normal detergents impair wicking by causing the fabric to retain moisture. This impairs the wicking process & makes the base layer wet, heavy & slow to dry. Wool Wash enhances & revitalises the natural performance characteristics of Merino Wool so your garments wick better, breathe better & stay lighter. Its not just about performance, you wouldnt wear everyday clothes that had not been washed regularly, 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. Easy to use as it cleans & conditions at the same time. Enhances & revitalises the natural wicking properties of woollen base layers & increases breathability. This helps the fabric to spread sweat, dry quickly, & keep you more comfortable in all conditions. Refreshes your woollen base layers by deodorising & maintains freshness by preventing odour build up when in use. Maintains the softness of your woollen base layers. Outperforms household detergents & fabric conditioners at improving wicking, accelerating drying, & removing & preventing odour.
