A long-sleeve button-down shirt in a medium Yale blue with a clean, matte finish and a pointed collar. White buttons contrast sharply against the blue fabric, and the tailored body narrows from chest to waist for a defined silhouette. The cuffs close with a single button.

Cut from Italian stretch fabric, this shirt delivers four-way flexibility and a wrinkle-free finish that lasts all day. Twenty-six individual fabric pieces are assembled with German stitching for precise, durable construction.

Conceived in Paris and built around an MIT-engineered fit algorithm developed from 30 million male body profiles, this Fibonacci shirt improves posture and creates a V-shape silhouette. It is precision engineering in service of effortless West Coast style.

Machine wash cold, hang dry. Available in sizes S to 5XL.
