I love these bibbed rain pants. They are so pratical - layer them with a sweater for a muddy day, with a fun rain jacket (because most brands only carry rain jackets), or with a winter coat on a cool (but not cold day).

The Washing Instructions from CeLaVi indicate that these can be washed in the washing machine at a MAX of 40C. We'd recommend attempting to spot clean with a soft cloth and some soap in the bathtub before attempting the washing machine.
No Fabric Softener should be used.
Powdered detergent is preferrable to liquid detergent, as liquid detergents can include components that will stick the fabric, reducing the waterproof and breathability.
Hang to dry.
