A long-sleeve button-down in a bold, saturated red with a smooth, jersey-like surface that drapes close to the body. The pointed collar sits cleanly, and tonal red buttons blend seamlessly into the front placket for a monochromatic effect. The fabric moves fluidly with every gesture, giving the shirt a relaxed, second-skin quality.

Cut from a four-way stretch performance fabric sourced from Italian mills, this shirt delivers unrestricted movement with a wrinkle-resistant, moisture-wicking finish. The lightweight construction breathes well and recovers its shape after a full day of wear.

The Eins silhouette, designed in Paris and shaped by an MIT-engineered fit algorithm based on 30 million body scans, tapers at the waist and broadens through the chest for a confident, V-shaped profile. A bold red shirt for the man who leads with color, equally at home under a black blazer or worn open-collared with dark jeans, grounded in West Coast confidence.

Machine wash cold and hang to dry. Available in sizes S to 3XL.
