D4621 - 14oz "Bengala" Natural Dye Selvedge - Type III Jacket

The D4621 “Bengala” Type-3 Jacket from Studio D’Artisan takes a timeless silhouette and infuses it with one of Japan’s most storied dyeing traditions. Made from 14oz Japanese selvedge denim, this piece is dyed using Bengala - a natural pigment extracted from iron oxide that’s been used for centuries to create earthy, rust-toned fabrics while also enhancing durability. The result is a rich, warm hue that deepens and evolves with wear.

Staying true to the classic Type-3 design, SDA adds subtle refinements throughout: custom iron buttons, selvedge accents, and precise sewing that highlight their masterful construction. The weight and structure of the fabric make it a perfect transitional piece — soft enough to move in, but heavy enough to stand up to years of wear. Made entirely in Japan, this jacket captures the brand’s dedication to craft and cultural storytelling.

Fit Notes: Studio has a really trim fit in general, but not with this jacket. Tommy is wearing a 42 in this jacket, which fits how he was expecting. This is a pretty traditional type iii fit. We would definitely recommend sizing up once, at least. Tommy is 5'10," 162lbs with a 40" chest.
