A long-sleeve button-down in a deep, saturated navy with a smooth, almost liquid surface that catches the light with a subtle sheen. The pointed collar is clean and sharp, and tonal dark buttons blend into the front placket for a seamless, monochromatic look. A dark contrast lining at the inner placket provides a glimpse of texture when the collar is left open.

Cut from a four-way stretch blended fabric sourced from Italian mills, this shirt moves with the body while maintaining a polished, wrinkle-resistant appearance. The stretch construction makes it ideal for long days that demand both comfort and a sharp look.

The Eins silhouette, designed in Paris and shaped by an MIT-engineered fit algorithm based on 30 million body scans, tapers through the waist and broadens at the chest for a confident, posture-improving profile. This is a go-to navy shirt for the man who wants performance and elegance in one garment, rooted in West Coast practicality.

Machine wash cold and hang to dry. Available in sizes M to XXL.
