Descartes Ascension Navy Blazer

A navy blue single-button blazer with a bold white windowpane check pattern. The contrast grid adds a graphic quality that reads classic British tailoring through a contemporary lens. Red accent details at the pocket trim and a branded sleeve patch add playful touches, while the notched lapels and clean pocket flaps maintain a sharp, traditional structure.

Cut from Italian cotton-blend fabric with a smooth hand and a hint of stretch, this blazer holds its shape through hours of wear without feeling restrictive. The lightweight construction makes it suitable for both indoor events and outdoor summer evenings.

Paris-designed with German stitching and an MIT-engineered fit algorithm, the Descartes blazer delivers a slim, modern fit that follows the shoulder line and tapers at the waist. The windowpane pattern reflects a West Coast willingness to take a classic code and make it personal.

Dry clean only. Available in sizes S to 3XL.
