Fibzip Marthyr Blue Shirt

This long-sleeve Fibzip dress shirt features a deep navy-blue body with a concealed front zipper closure that replaces the traditional button placket, creating a sleek, minimalist silhouette. A structured spread collar anchors the neckline, while the iridescent quality of the stretch fabric reveals subtle purple-blue undertones as it catches the light. The clean zip-front design lends a contemporary, fashion-forward edge.

Constructed from a four-way stretch blended fabric sourced from Italian mills, this shirt delivers moisture-wicking comfort and a wrinkle-resistant finish. The lightweight fabric moves naturally with the body while maintaining a polished, structured drape.

Designed in Paris and shaped by Maceoo's proprietary MIT fit algorithm, developed from data on 30 million men, this Fibzip silhouette combines the tailored precision of the Fibonacci cut with a modern zip-front closure. Twenty-six precision-cut pieces and German stitching ensure a refined fit throughout.

Wash cold and lay flat to dry. Available in sizes S to 4XL.
