- The Type 1 denim jacket traces its origins back to the early 20th century, when durable denim outerwear was developed for workers. Characterized by its single chest pocket, front pleats, and adjustable back cinch, the design reflects the practical needs of early workwear while establishing the foundation for all later denim jackets.
The Boncoura Type 1 Jacket draws inspiration from designs produced around the 1930s, before World War II. It features a classic flap chest pocket and a traditional two-prong cinch back.
The jacket is made from Boncoura’s special 15oz “Ikemen” denim, slowly woven on vintage shuttle looms under low tension. This method allows the fabric to retain a natural texture and depth while maintaining a strong sense of structure and resilience.
The silhouette has been refined by Boncoura with a roomy chest and armholes, allowing for comfortable movement while maintaining the character of the original design.
While preserving classic vintage details, the jacket also features a T-Back construction. This design uses two panels of denim joined at the center back seam, forming a shape that resembles the letter “T”, a detail highly appreciated by vintage denim enthusiasts and collectors.
