Billy Trench Coat Care Guide
For all your washes, we recommend using a European Ecolabel detergent, which is gentler on fibers (helping to extend the life of your garments) and less harmful to the environment (and to health).
The European Ecolabel is a European label established in 1992. It is awarded to products (goods or services) that meet environmental and health criteria defined at the European level. This label is the only official eco-label recognized across all European Union member countries. It guarantees ecological and health quality, as well as functional quality, and takes into account the product’s life cycle and overall environmental impact. (1)

To care of your Billy trench coat, the best approach is to clean small stains regularly with a damp cloth, rather than putting it straight in the washing machine. The gabardine has a water-repellent finish, but machine washing tends to reduce its effectiveness.
For a full machine wash, we recommend:
• Wash it inside out in cold water (or at 30°C) using a European Ecolabel-certified detergent. A short cycle with a spin at 600 rpm is sufficient.
• Let it air dry, properly positioned on a wooden hanger to avoid unwanted creases and excessive wrinkling.
• Iron very lightly on a low setting, or ideally not at all. Note that ironing can also reduce the effectiveness of the water-repellent finish..
In general:
• Store it on a hanger (not folded) to avoid creases, ideally in your wardrobe away from direct light.
