- STEP 1 Shake bottle well before use to activate the formula. STEP 2 Spray all over a clean, damp garment from 10-15cm away until garment is fully treated. (We would recommend using a technical performance wash to clean the garment before application. Always follow the washing instructions on the label.) STEP 3 Remove any excess treatment with a clean cloth. STEP 4 Allow treatment to cure. Air dry by hanging up and leave to dry overnight before wearing jacket in wet conditions again. STEP 5 After application, the outside of the garment will be hydrophobic - in other words, water repellent. The water will bead upon impact and roll of the garment, helping to keep the rider dry! Top Tip! Best applied to a clean, damp garment for optimum results.
