Fan gear that only works inside the stadium is not really fan gear. This Borussia Dortmund training jersey is cut to leave the stadium.
Cut sits between slim and boxy, so it layers without looking oversized. Sizing runs on the US scale, so the usual letter size is the right call.
Construction is straightforward: a breathable mesh body, vented side panels, heat-sealed lettering and a V-neck collar. Cut for men, sized men's S–3XL. Sizing follows the US scale, so the letter size you normally wear is the right call. It ships with the name and number already applied — nothing to iron or assemble on arrival.
It reads as Borussia Dortmund gear anywhere, but the palette points straight back to Dortmund, Germany and Signal Iduna Park.
