Some jerseys are worn once a season. This Borussia Dortmund warm up one is worn every week — Guirassy on the back is the reason.
Cut sits between slim and boxy, so it layers without looking oversized. The mesh body hangs flat instead of bunching at the waist.
Fan-version build with the Borussia Dortmund colourway and Guirassy lettering applied front and back — the detail that separates it from a plain team tee. 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.

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.
Is the fabric breathable enough for a full match?
Yes. The mesh body and vented side panels move air far better than a standard cotton tee, keeping you comfortable for the full 90 minutes.
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 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.
