The piece is made from a cotton-rich blend of 88.5% cotton and 11.5% polyester, giving it a substantial, structured handfeel with excellent shape retention and wind-blocking performance. The fabric has a firm, dry-touch quality that holds the retro workwear silhouette cleanly, while the cotton content keeps the piece breathable for comfortable wear. The standard fit, long sleeves, and regular length make it well suited to casual, layered outfits in autumn, pairing naturally with denim or utility trousers for a vintage-inspired look.
