Most Willy Chavarria items here are cotton-based jerseys, sweats, and woven pieces, with some nylon and viscose blends. Follow the label instructions—usually gentle machine wash or dry clean for structured outerwear and viscose-blend pants. Wash graphic and logo T-shirts inside out to help preserve prints. With correct care, the fabrics are designed to keep their structure and color so the silhouette stays sharp over multiple seasons.
