When it comes to day-to-day care of your denim item, we would always recommend checking the care label on each individual piece and follow the instructions carefully. Prolong the life of your denim by hand washing inside out or by putting in the washing machine. Clean in a cold water and use a mild detergent. Avoid excessive exposure to sunlight, bleach and harsh chemical cleaners. For jackets that are sure to see you through the rest of the season, shop the collection today.
