With proper care, your Bulletprufe jeans and chinos will provide years of use. As with any denim, your Bulletprufes will fade over time and give you that classic worn look. But to lock in the color and prevent fading, we recommend that you add two cups of white vinegar to the water when you wash them. Hand or machine wash them in cold water and hang dry. Please note - the first time you wash your Bulletprufes, please wash them by themselves as some color may bleed which could potentially discolor other items.
