Wash on the reverse side with neutral detergents to preserve color and fabric integrity. Avoid soaking, direct sunlight, and bleach, which can compromise the garment's quality. For drying, use low-temperature tumble dry settings (maximum 30°C/90°F) or air dry for optimal longevity. If ironing is necessary, apply low heat or use a steamer to maintain the sweatshirt's lightweight construction and oversize fit without damage.
