A clean outer layer built for movement, storage, and daily wear, the Black Shirt Jac bridges the gap between a button up overshirt and an insulated jacket. The solid black exterior keeps the profile low and versatile, while the structured collar, button cuffs, and chest pockets give it a sharp utility shape.
Inside, oversized stash pockets add room for gloves, notebooks, and daily carry essentials without overbuilding the silhouette. The relaxed true to size fit layers easily over a tee, thermal, or light base layer while still looking intentional on its own.
