When Koller pulled on the Borussia Dortmund Warm Up jersey for the 2025-2026 campaign, fans took notice. This is that shirt: the season's design, the name and number on the back, and a fit built for the stands rather than the pitch.
The Design
Football design is a language, and this shirt speaks it fluently. The 2025-2026 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.

Fit & Fabric
A quick note on versions: this is the supporter's cut of the jersey. Same colors, same crest, same name and number as the on-pitch design, with a relaxed fit that makes it wearable seven days a week rather than ninety minutes.

+What season is this Borussia Dortmund Warm Up shirt from
This design is the 2025-2026 edition — the campaign's specific colorway, crest, and lettering. Season-specific shirts are how collectors mark eras, and this one captures that campaign's look faithfully
+What colors does this Borussia Dortmund Warm Up shirt come in
The Black edition is featured here. Home, away, and third colorways for the same season each have their own product page, linked from the collections below
+Is the crest embroidered or printed
The crest is applied in the style of the season's design — modern shirts typically use heat-bonded crests, retro reproductions often recreate the era's sewn-on look. Either way, the finish matches the design it celebrates and is built to survive regular cold washing
+Is this shirt a good gift for a Borussia Dortmund Warm Up fan
For a Borussia Dortmund Warm Up supporter, this shirt is a guaranteed win. The Koller name and number carry the emotional weight; the size chart handles the fit. It is the gift equivalent of a goal celebration
+How do I pick the right size when buying as a gift
Measure a shirt they already love and compare to the chart — that is the reliable path. Or simply order their standard tee size; exchanges are free within 30 days if the fit is off
+Is this a good shirt for everyday wear, not just match days
Yes. These shirts have crossed firmly into streetwear, and the lightweight knit is genuinely comfortable for daily wear. Pair it with jeans for a casual look or wear it loud on match day
Grab your size, add custom name and number printing if the mood strikes, and this Borussia Dortmund Warm Up shirt with Koller on the back is ready to wear the moment you open the box. Two shirts in one order cover most fan wardrobes easily.
