Boncoura '41 Brown Heavy Corduroy Chinos (Relaxed Tapered Fit)

Size Guide
Bon' is back with another masterpiece!

The classic 41 style chinos are a historic WWII design that has such elegant detailing yet always had a baggy/oversized fitting for modern-day standards. Bon has taken the elegance of the original pocket and waist designs to make for a relaxed tapered fit that's timeless!

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 for a beautiful sheen. It takes 6-9 months to bring from raw materials to the final fabric.

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 tailor standard 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 relaxed tapered fit has a formal silhouette that doesn't look 'baggy' yet these are so comfortable for daily use!
