Indigo Cook Serge Nimes Jacket

The Nîmes Jacket takes its inspiration from classic French workwear, with a boxy silhouette reminiscent of a coverall. A subtle detail lies in the brass buttons, which are engraved with a seabird flying busily with needle and thread in tow—an emblem of quiet industriousness.

The fabric, which we’ve named “Cook Serge,” was inspired by vintage European chef uniforms and woven in a cotton twill similar to denim. It may not be showy, but its textured, irregular finish and solid durability reflect the understated strength of Japanese craftsmanship.

This original serge is woven from indigo-dyed slub yarns, creating a gently undulating pattern with a sense of depth. As you wear it, the indigo will gradually fade, bringing out the evolving character of the fabric—a hallmark of 45R’s thoughtful approach to making clothes.
