Military surplus has inspired generations of menswear, and the Corbin Service Jacket follows that tradition. Lightweight enough for spring and cool summer evenings, it borrows the clean lines and utility-focused details of classic field jackets without feeling overly rugged. Large chest pockets add both storage and character, while a vintage-style bent wire zipper pull gives the piece a subtle old-school touch. Layer it over a tee or wear it as a light outer layer when the weather can't quite make up its mind.
