Each Barbour garment has a label attached showing the washing instructions. Generally all Barbour waterproof breathable outerwear can be machine or hand-washed at 30°C. Barbour recommends that you use non-biological washing powders only and no fabric softeners as these prevent the durable water repellent treatment (DWR) from working effectively. The garments can be tumble dried at a low heat setting, but once the machine stops they must be removed from the drum immediately. Barbour recommends the use of Nikwax Tech Wash (https://www.outdoorandcountry.co.uk/nikwax-tech-wash-300ml.html) and Nikwax TX. Direct Wash-In (https://www.outdoorandcountry.co.uk/nikwax-tx-direct-wash-in-300ml.html) for your breathable garments. Nikwax products are available at leading outdoor retailers. For specific washing instructions please see the garment care label on your product.
