The first thing you notice is weight. This training jersey uses breathable athletic mesh that hangs clean instead of clinging after a full game.
This is the training build rather than match-worn kit: the same Borussia Dortmund look, a fan-weight mesh body, and a cut that layers over a tee. Sizes run youth S–XL on the US scale. 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.
Cut sits between slim and boxy, so it layers without looking oversized. The name and number are heat-sealed rather than printed on top.

You are covered by our 30-day hassle-free guarantee with zero restocking fees. If the fit is not ideal, contact our support team and your first size exchange is completely free.
Are the Koller name and number details printed or pressed?
They feature durable heat-applied twill graphics, true to the original tournament kit aesthetic while staying machine-wash durable.
Does the Borussia Dortmund name and number come already applied?
Yes. The jersey ships with Koller name and number already heat-sealed in place — no ironing or assembly on arrival.
