Borussia Dortmund Warm Up · 2026-2027 · Black
Every football fan has a shirt that explains them. For fans of that era's Borussia Dortmund Warm Up, this is it: the 2026-2027 jersey, Koller (No. 8) on the back, and a design that needs no introduction to anyone who watched that season.
Shirt Card
Condition: Brand new with tagsTeam: Borussia Dortmund Warm UpSeason: 2026-2027Player: Koller — No. 8Colour: BlackFit: Relaxed fan fit
The Design
Football design is a language, and this shirt speaks it fluently. The 2026-2027 Borussia Dortmund Warm Up colorway, the era-correct typography on the back, the clean front — it is the kind of kit that looks considered from every angle.
Fan Version, Match Look
Player version or fan version? This is the fan version — the smart choice for supporters who plan to actually wear their shirt. The design is identical to the pitch template; the fit is simply friendlier for everyday use.

Frequently Asked Questions
+What is the fit like — slim or relaxed
The fit sits between slim and relaxed: athletic enough to look like a proper football shirt, roomy enough for all-day comfort. Fans who want a looser streetwear silhouette usually go one size up, and that combination is honestly how most people wear them
+I am between two sizes — which should I pick
Size up. A half-size of extra room is barely noticeable, while a shirt that pulls at the chest gets uncomfortable fast. The chart measurements make the final call easy
+Do you have a size chart in inches and centimeters
The chart above shows both inches and centimeters for every size, so US and EU shoppers can each read the numbers they know. Measure your favorite tee and compare — it takes thirty seconds and removes all doubt
+Is this a good shirt for everyday wear, not just match days
Absolutely — that is honestly how most fans use them. Polyester football shirts double as summer tees, gym tops, and streetwear layering pieces. The breathable fabric and bold colors have made them a year-round wardrobe staple far beyond the stadium
+How do I remove stains from a football shirt
Cold water and mild detergent handle most match-day stains. For stubborn ones, dab (do not rub) with diluted vinegar before a normal cold wash. Bleach is the enemy of colored football shirts
+What is the difference between the fan version and player version shirt
Same design, two cuts. Player version: athletic fit and performance fabric like the pros wear. Fan version: identical colors and crest in a relaxed cut built for the stands, the street, and the sofa. Both carry Koller's name and number
+Which player and number is printed on this shirt
This shirt carries Koller with the number 8 — the name and digits Koller wore for Borussia Dortmund Warm Up that season. The lettering style matches the season's typography, so the back looks exactly as it did on the pitch
Ready to wear Koller's name on your back? Pick your size from the selector — and if you would rather have your own name and number, custom printing is one option away at checkout.
