2025-2026 Borussia Dortmund Warm Up Jersey (Black) (Gross 13) is a fan version football shirt for the 2025-2026 season, produced for supporters in a breathable polyester build with a Black colourway. It is a supporter-tier replica rather than a player-issue garment, so the fit runs true to standard sizing and the price stays accessible for everyday wear.

The Design
Colorways earn their place in football history, and this 2025-2026 design is a faithful recreation: every stripe, block, and accent placed as Borussia Dortmund Warm Up wore them. The black palette reads instantly to any fan of the club.
Fan Version
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.
Common Questions About This Shirt
+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 Gross's name and number
+Is this shirt the same design Borussia Dortmund Warm Up wore on the pitch
Yes — this design follows the colorway and crest layout of the shirt worn that season. The visual identity is the same; the fan cut simply adjusts the fit for everyday comfort while keeping every design element in place
+How do I contact customer support
Reach us at jerseyhelp@outlook.com anytime. Order number in the subject line speeds things up; replies land within 24 hours
+What season is this Borussia Dortmund Warm Up shirt from
It is the 2025-2026 design, complete with that campaign's colors and typography. The details are era-accurate, which is what separates a proper season shirt from a generic club tee
+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 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
Ready to wear Gross'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.
