The Oak Heavyweight Flannel is exactly what it sounds like, a real heavy weight flannel jacket outer layer. This thing is strong and solid. You get a button up front, double button cuffs, button closure chest pockets, and custom Brixton buttons throughout. A straight hem, flannel outer, and quilter inner make this thing a solid choice. Brixton detailing throughout. Constructed of 90% polyester, 10% wool. Available in colorways as seen below. Model wears a medium.
