Ajax · 2023-2024
Some shirts you buy for the badge. This one you buy for the name. The 2023-2024 Ajax shirt with Klaassen (No. 6) on the back is the kind of kit that starts conversations in any room of football fans — the season, the player, the number, all in one wear-anywhere shirt.
The Design
Look closely and the details hold up: the crest placement, the collar shape, the balance of the Ajax colors — all true to the 2023-2024 design. From two meters away it is simply a great-looking football shirt, which is the entire point.
Fit, Fabric & Details
This is the fan version of the shirt — identical design to the match-day template, cut for real life. The roomier fit and soft-touch knit make it a shirt you actually reach for, whether that is for the stadium, the street, or the sofa on away nights.

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
Go with the larger size. Football shirts layered under jackets or worn to the pub before kick-off feel better with a touch of extra room, and a slightly relaxed fit is the most common way fans wear them anyway
+Do you have a size chart in inches and centimeters
Yes — the size chart on this page lists chest measurements in inches with centimeter conversions alongside, covering every size from kids small to adult XXL. Sizing in metric or imperial, you can order with confidence
+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
The player version mirrors what athletes wear: slim athletic cut, lightweight performance knit, heat-applied crest and numbers. The fan version keeps the identical design in a roomier everyday cut with softer fabric — most fans choose it precisely because it is comfortable beyond match day
+Is this shirt available in kids and youth sizes
Yes — this design is offered in a full size run that includes kids and youth options where available. Use the size chart for chest measurements, since junior sizing varies more between brands than adult sizing does
Grab your size, add custom name and number printing if the mood strikes, and this Ajax shirt with Klaassen on the back is ready to wear the moment you open the box. Two shirts in one order cover most fan wardrobes easily.
