Belgium FIFA ™ T · 2026 · Casual · No. 14 · Kids
Belgium FIFA World Cup 2026™ T-Shirt (Red) - Kids (Mertens 14) is a fan version football shirt for the 2026 season, produced for kids in a breathable polyester build with a Red colourway.

Belgium FIFA ™ T · 2026
What makes a shirt worth owning? A player worth backing, a design worth wearing, and a story worth retelling. The Belgium FIFA ™ T 2026 shirt with Mertens (No. 14) printed on the back checks all three.
The Design
Look closely and the details hold up: the crest placement, the collar shape, the balance of the Belgium FIFA ™ T colors — all true to the 2026 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.

Before You Add to Cart
+What season is this Belgium FIFA ™ T shirt from
This design is the 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 Belgium FIFA ™ T shirt come in
The Red 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 the crest embroidered or printed
Crest application follows the season's design: bonded crest on modern templates, era-style stitched crest on retro reissues. Both hold up to years of proper washing
+Is this shirt a good gift for a Belgium FIFA ™ T fan
It is about as safe as football gifting gets — a Mertens shirt in the fan's size with their club's colors. Add custom name and number printing for kids and you have the gift they talk about for months. Birthdays, holidays, and match-day surprises: this one rarely misses
+How do I pick the right size when buying as a gift
Discreetly borrow a shirt the recipient already wears, measure it pit-to-pit, and match that number to our size chart. Cannot borrow one? Their usual t-shirt size works for most adults, and the 30-day exchange window is the safety net for gift misses
+What makes a better gift — home or away shirt
Home shirts are the iconic choice — the colors every neutral recognizes. Away shirts are the connoisseur's pick, marking specific seasons and famous away wins. If unsure, home is the safe classic; if the fan already owns the home version, the away shirt completes the set
+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
Match day is coming. Choose your size, personalize the back with Mertens'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.
