A charcoal grey long-sleeve button-down featuring an all-over geometric interlocking pattern in tonal dark grey. The print creates a subtle optical texture that adds depth without loudness, making it a versatile choice for both business and evening settings. The spread collar sits neatly and the slim cut follows the body without restriction.

Cut from Italian cotton with a smooth, wrinkle-resistant finish, this shirt delivers a polished look with minimal maintenance. The fabric breathes easily and maintains its structure from morning meetings through to after-hours plans.

Assembled from 26 precision-cut pieces with German stitching, the Fibonacci line uses an MIT-engineered fit algorithm to create a dress shirt that contours the chest and shoulders while allowing full range of motion. Paris-designed with a West Coast lifestyle attitude, it turns a grey shirt into something worth noticing.

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