HappyRainyDays rainwear can be washed at 30 degrees, without spin-drying. We recommend using no washing powder but OutdoorWash, which will ensure the continuation of our rainwear’s water-repellent and breathing properties. Check detergents. To conclude, in order to retain the colours we advise that you wash the clothing inside out. Dry We advise you not to dry your rainwear in the tumble dryer. For best results simply hang it out to dry.
