A long-sleeve dress shirt in muted olive green with a smooth, performance-stretch finish. The spread collar sits clean and structured, and silver engraved-logo buttons run the full placket. The earthy green tone reads sophisticated and contemporary, working across both casual and semi-formal settings.

Crafted from premium Marthyr performance fabric, this shirt delivers exceptional four-way stretch, moisture wicking, and wrinkle-free properties. The silky-smooth composition stretches visibly when pulled, demonstrating the fabric's remarkable flexibility while snapping cleanly back into shape.

Designed in Paris and shaped by an MIT-engineered fit algorithm developed from data on 30 million men, the Eins Marthyr pulls the shoulders back and tapers through the torso for a natural V-shape silhouette. Pair with tan chinos for a smart casual look or with black trousers for evening.

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