Military Down Shirt from Japan's Taion.

A standout from the Taion MILITARY LINE, this Down Shirt blends rugged utility with high-performance warmth. It features functional dual chest pockets and signature side-slit zippers—a detail designed to increase your range of motion and unlock dynamic layering possibilities. Whether worn as a lightweight outer layer over a tee or tucked under a heavy coat, it’s a versatile daily essential that’s easily hand-washable at home.

Taion typically follows standard Japanese sizing, which runs small compared to Western brands; most customers find they need to size up one full size from their usual European or American size for a comfortable fit.
