BONCOURA Heavy Corduroy "Dog Ear" Sport Jacket (Navy)

Bon' is back with another masterpiece!

This classic design is inspired by the elegant vintage English Baracuta 'sports' jackets that were functional yet maintained a formal 'gentlemen' look.

Bon' have a passion to develop their spectrum of fabrication. This one might bring back memories of vintage Ralph Polo garments with tastefully large ridged corduroy. To make this memory to another level, Bon' have created a heavyweight corduroy with extra-large ridges and a silky smooth surface without a 'scratchy' feeling. They use full-grain natural cotton to make up a beautiful sheen. It takes 6-9 months to bring from raw materials to the final fabric, from a vintage machine.

The thread dyed colourway will gradually gain a soulful, softly faded appearance with long term usage.

Aside from the enhanced texture, this allows the fabric to maintain warmth and keep you protected from the cold wind. The reverse side itself is truly another level. The appearance is like some jacket shell standard herringbone twill with a very smooth feeling.

From the construction, the custom developed brass zip, to the herringbone twill lining, this one is a true example of Boncoura's pride to create next-level products.

The silhouette is simple and elegant. We love the adjustable cuffs and waistband giving you flexibility for changing weather and occasions. The collar and waist pockets are balanced, so perfect for a timeless look!
