Belgium · 2026-2027
When Mertens pulled on the Belgium shirt for the 2026-2027 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
Look closely and the details hold up: the crest placement, the collar shape, the balance of the Belgium colors — all true to the 2026-2027 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.

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 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 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
+How do I order this Belgium shirt
Choose your size from the selector, add the shirt to cart, and checkout with your preferred payment method. If you want custom name and number printing, select that option before adding. The whole process takes under two minutes
+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
+What is the fit like — slim or relaxed
It is an athletic cut — shaped through the shoulders with a slight taper, but comfortable through the torso. If you prefer a boxier retro look, sizing up once gives you exactly that
+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
+Which player and number is printed on this shirt
The back reads Mertens 14, applied in the lettering style of that Belgium season. It is the exact pairing fans remember from the campaign
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.
