2023-2024 Ajax Third Shirt (Klaassen 6) is a fan version football shirt for the 2023-2024 season, produced for supporters in a breathable polyester build with a team 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.

Ajax · 2023-2024
When Klaassen pulled on the Ajax shirt for the 2023-2024 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 2023-2024 Ajax 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 & Details
A quick note on versions: this is the supporter's cut of the shirt. 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
+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 Klaassen's name and number
+Is this shirt the same design Ajax wore on the pitch
The colors, crest placement, and design language match the season's on-pitch shirt. It is the look fans recognize instantly, made comfortable for daily wear
+How do I contact customer support
Email jerseyhelp@outlook.com with your order number and question — the team replies within 24 hours, usually faster on match days off. Size advice, order changes, exchanges: the same address handles everything
+What season is this Ajax shirt from
It is the 2023-2024 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 Ajax shirt come in
This listing is the club colorway. Where Ajax released home, away, and third variations for the season, each appears as its own listing — so you can build the full kit collection at your own pace
+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
+Which player and number is printed on this shirt
The back reads Klaassen 6, applied in the lettering style of that Ajax season. It is the exact pairing fans remember from the campaign
Match day is coming. Choose your size, personalize the back with Klaassen's name if you like, and checkout takes under two minutes. 30-day exchanges and a support team that actually replies keep the whole thing risk-free.
