A long-sleeve dress shirt in clean white with a smooth, performance-stretch finish. The spread collar sits crisp and structured, and dark engraved-logo buttons run the full placket, providing a refined contrast against the white fabric. The overall look is minimal, polished, and essential.

Crafted from premium Marthyr performance fabric, this shirt delivers exceptional four-way stretch, moisture wicking, and wrinkle-free properties. The silky-smooth white composition maintains its brightness and tailored shape through extended wear, making it a reliable all-day performer.

Designed in Paris and shaped by an MIT-engineered fit algorithm built from data on 30 million men, the Eins Marthyr pulls the shoulders back and tapers through the torso for a defined V-shape silhouette. This is the performance white shirt that replaces your entire rotation.

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