- The removable pouch pocket can be used to store rubbish, wet items etc. and can be removed to wash separately with ease.
- Only machine wash as a last case scenario. Use a Nikwax technical wash on a cold / gentle cycle and leave it hung to dry at room temperature. Never use fabric softener or a detergent. As with any waterproof product each machine wash will reduce the fabrics water repellence, hence why we have designed our product to reduce the need for this.
