Machine Wash (Preferred) Set the washing machine temperature preferably to 15°C, maximum 30°C, and select the delicate or hand wash cycle. Use a mild liquid detergent. Hang the product on a hanger while still wet until it is fully dry. Iron the product on the lowest steam setting, pressing gently on the fabric. Iron the inside of the fabric, not the outside.
Hand Wash Immerse the fabric in cold water (0-20°C) with a mild liquid detergent for no more than 5 minutes. For stains, gently rub while keeping the fabric submerged. Rinse with water containing a quarter cup of vinegar to remove soap and restore shine and color. Then rinse with cold water. Squeeze out excess water by rolling the product in a towel. Lay it flat on the towel to dry. Hang it on a hanger while still slightly damp until fully dry. Iron the product on the lowest steam setting, pressing gently on the fabric. Iron the inside of the fabric, not the outside.
Special Care Suits and jackets should be dry-cleaned only.
Attention! To prevent color transfer from leather labels, remove clothing from the washing machine immediately after washing or spinning. Never leave clothing in the machine for an extended period. We conduct extensive wash tests on all our products before they reach stores or are sold online. Follow this advice; otherwise, we cannot accept returns.
