2025-2026 Ajax Third Shirt (Kids) (Klaassen 18)

2025-2026 Ajax Third Shirt (Kids) (Klaassen 18) is a fan version football shirt for the 2025-2026 season, produced for kids in a breathable polyester build with a team colourway.

Ajax · 2025-2026
The 2025-2026 Ajax shirt — worn by Klaassen (No. 18), remembered by supporters. This fan version brings the same colors and lettering in a comfortable everyday cut, ready for match day, the gym, or a summer afternoon.
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 2025-2026 design. From two meters away it is simply a great-looking football shirt, which is the entire point.
Fit, Fabric & Details
Player version or fan version? This is the fan version — the smart choice for supporters who plan to actually wear their shirt. The design is identical to the pitch template; the fit is simply friendlier for everyday use.

Keeping It Fresh
Cold wash, inside out, hung to dry — three habits that keep football shirts looking new for seasons. Skip the dryer and the iron-on-print combo and this shirt ages gracefully.
Before You Add to Cart
+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
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 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
+Is this shirt a good gift for a Ajax fan
For a Ajax supporter, this shirt is a guaranteed win. The Klaassen 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 shirt available in kids and youth sizes
Youth and kids sizes appear in the size selector whenever they are in stock for this design, alongside adult small through XXL. Junior sizes follow the same chest-measurement logic, so a quick check of the chart works for younger fans too
Ready to wear Klaassen'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.
