Every home crowd has that one moment it waits for. For Borussia Dortmund fans it usually involves Koller, and this training jersey is built for that moment.
Cut sits between slim and boxy, so it layers without looking oversized. The hem sits a touch longer in back for coverage.
The design follows the Borussia Dortmund training look — team colours, Koller name and number on the back, and the same silhouette worn in the stands. It ships with the name and number already applied — nothing to iron or assemble on arrival. Machine wash cold, tumble dry low, and it is ready to wear again the next morning.
It reads as Borussia Dortmund gear anywhere, but the palette points straight back to Dortmund, Germany and Signal Iduna Park.

Frequently asked questions
What if the jersey does not fit when it arrives?
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.
Will the fit work for layering over a hoodie in cold weather?
US letter sizing with a relaxed chest and shoulder cut leaves room for a hoodie or thermal underneath without pulling at the seams.
What size Borussia Dortmund jersey should I order if I am between sizes?
US letter sizing runs true. If you want a relaxed layer for cold-weather games, take the size up; for a closer fit take the smaller one. The first size exchange is free either way.
What is the difference between this fan version and an on-field jersey?
This is fan apparel built for supporters: a lightweight mesh body and a relaxed cut, not the athletic cut worn by players on the field.
