The piece is made with a 100% cotton outer fabric, giving it a natural, breathable feel that suits the American vintage aesthetic and casual, everyday wear through autumn and winter. The cotton shell has a substantial, structured quality that works well with the retro, street-inspired look, while the solid color and paneled construction keep the style clean and easy to layer. Inside, the lining is 100% polyester, which provides a smooth interior layer that helps the piece slide on easily and adds durability for regular wear. The combination of a cotton outer and polyester lining supports the relaxed, vintage-inspired design while keeping the piece comfortable for casual outings.
