Uniforms change, rosters turn over, and the Celtic palette stays. This retro build is the current chapter of that.
Fan-version build with the Celtic colourway and Grant lettering applied front and back — the detail that separates it from a plain team tee. Machine wash cold, tumble dry low, and it is ready to wear again the next morning. Every order is checked before dispatch and travels with end-to-end tracking. The colourway is matched to the on-field look rather than to a screen approximation.
It reads as Celtic gear anywhere, but the palette points straight back to Glasgow, Scotland and Celtic Park.
The body is cut a touch longer in back, which is what keeps it put through a standing ovation. The hem sits a touch longer in back for coverage.

Care Guide
Machine wash cold inside out with a mild detergent, then tumble dry low. Skip fabric softener and high heat, and do not iron directly over the lettering.

Frequently asked questions
What if the jersey does not fit when it arrives?
You are covered by our 30-day hassle-free guarantee with zero restocking fees. If the fit is not ideal, contact our support team and your first size exchange is completely free.
Does this jersey celebrate Grant's career?
Yes. This is a tribute design built around Grant's legacy — the seasons fans still bring up. The colours and lettering follow the era Grant played in, which is the whole point of the piece.
Is this Celtic retro jersey good for gifting?
It is a common gift choice: the name and number are already applied, US sizing is printed on the label, and if the fit is wrong the first size exchange is free.
What size Celtic jersey should I order if I am between sizes?
US letter sizing runs true. If you want a relaxed layer for cold-weather games, take the size up; for a closer fit take the smaller one. The first size exchange is free either way.
