The long-sleeve OS Trachten flannel. This is the cold-weather version of the field shirt that started the collection — same traditional construction, same Bavarian sensibility, now in heavyweight 100% cotton flannel built for autumn and winter.

Deep forest green, navy, and sage check. Small embroidered detail on the chest pocket — understated, the way OS Trachten does it. Shark collar, single patch pocket, copper-tone buttons throughout. Full-length sleeve, regular fit.

No zippers, no contrast panels, no roll tabs. Just a well-made German flannel shirt that will outlast everything else in the rotation.
