Some players change how a fan dresses on game day. Gross is one of them, and this Borussia Dortmund training jersey is the short version of why.
Fan-version build with the Borussia Dortmund colourway and Gross lettering applied front and back — the detail that separates it from a plain team tee. Machine wash cold, tumble dry low, and it is ready to wear again the next morning. Every order is checked before dispatch and travels with end-to-end tracking.
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. Care is simple: machine wash cold inside out, tumble dry low.

Fit & Sizing
US youth sizing (youth S–XL). The cut is relaxed rather than slim, so there is room to move and room to grow. The usual letter size is the right starting point.

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.
Can this retro kit be worn for casual summer wear?
Yes. The lightweight breathable mesh makes it a staple for warm-weather viewing with friends, five-a-side matches, or casual streetwear.
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.
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.
