As a general rule, nylon and puffy, down-filled jackets, coats, and vests can all go in the washing machine. Wash them on a gentle cycle with cold water and regular detergent.
Can you wash a North Face jacket in the washing machine?
Place the jacket in a front-loading washing machine on a gentle cycle. Top-loading machines with an agitator will likely damage the construction of the jacket. Warm water and a mild powder detergent are recommended. For best results, repeat the rinse and spin cycles to help remove all soap residue.
