A Borussia Dortmund jersey is never only about the season — it is about whose name you want on the back. This warm up build puts Koller there for men.
This is the warm up 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 men's S–3XL on the US scale. The colourway is matched to the on-field look rather than to a screen approximation.
It reads as Borussia Dortmund gear anywhere, but the palette points straight back to Dortmund, Germany and Signal Iduna Park.
Shoulders are set for movement rather than for the mannequin. Mesh panels run the side seams to move air.

Yes. The lightweight breathable mesh makes it a staple for warm-weather viewing with friends, five-a-side matches, or casual streetwear.
How does this retro soccer shirt fit compared to modern slim-fit kits?
It captures the classic vintage silhouette — roomier through the chest and sleeves than modern slim-fit kits. If you prefer a tailored look, consider sizing down.
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.
