This jacket requires no setup. Simply put it on over your child's clothing. It is designed to be compatible with standard children's layering systems, fitting comfortably over fleeces, jumpers, or t-shirts. To ensure the longevity and effectiveness of its waterproof properties, proper care is crucial:1. Washing: Always refer to the care label inside the jacket. Typically, machine wash at 30°C with a technical cleaner designed for waterproof outerwear, or a mild liquid detergent. Avoid fabric softeners, as they can impair the waterproof finish.2. Drying: Do not tumble dry. Hang the jacket to air dry completely, away from direct heat sources. Ensure it is thoroughly dry before storing to prevent mildew.3. Re-proofing (Optional): Over time, the durable water repellent (DWR) finish may wear off. If water no longer beads on the surface, consider using a DWR re-proofing spray or wash-in product specifically designed for waterproof fabrics. Follow the product's instructions carefully.4. Storage: Store in a cool, dry place. Avoid compressing the jacket for long periods, which can affect the fabric's performance.5. Stains: For minor dirt, wipe clean with a damp cloth. For tougher stains, follow the general washing instructions.
