Borussia Dortmund Warm Up · 2026-2027
Beier — the name and number on the back of this shirt
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, Beier (No. 14) on the back, and a design that needs no introduction to anyone who watched that season.
Season Story
The design does the talking: the Borussia Dortmund Warm Up colors are laid out exactly as the club wore them that season, crest sitting proud on the chest and the lettering true to the campaign. It photographs like a proper football shirt — because it is one.

Care & Longevity
Collectors and everyday fans agree on the routine: cold water, inside out, air dry. Do that and both the fabric and the print stay sharp for years — the shirt you hand down, not the shirt you bin.
Common Questions About This Shirt
+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 Beier 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
+What makes a better gift — home or away shirt
Home is the classic gift; away is the insider's gift. Fans who already own the home shirt light up more over the away version — it shows you paid attention to their collection
+How do I order this Borussia Dortmund Warm Up shirt
Pick your size, add to cart, checkout — the standard three steps. Custom personalization, if you want it, is chosen at the product stage before the cart
+Will this shirt be restocked if my size sells out
Popular sizes and classic designs are restocked regularly, especially retro lines. If your size shows as unavailable, use the contact option — our team can often tell you the restock date before it is publicly listed, and fans on the early list rarely miss out twice
+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
Ready to wear Beier'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.
