This jacket requires no setup; it's ready to wear straight out of the packaging. It is compatible with standard children's clothing and can be easily layered over fleeces or thermals for added warmth in colder conditions. For care, it is essential to follow the specific instructions on the garment's inner care label. Generally, waterproof jackets should be washed on a cool cycle with a technical wash, avoiding fabric conditioners which can degrade the waterproof coating. Info needed: Always check the specific care label for detailed washing and drying instructions. Air drying is typically recommended over tumble drying to preserve the fabric's integrity and waterproof properties.
