Nobody agrees on which Celtic player deserves a jersey, which is exactly why this authentic one exists for the Mcstay camp.
Shoulders are set for movement rather than for the mannequin. Mesh panels run the side seams to move air.
Construction is straightforward: a breathable mesh body, vented side panels, heat-sealed lettering and a V-neck collar. Cut for men, sized men's S–3XL. Sizing follows the US scale, so the letter size you normally wear is the right call. It ships with the name and number already applied — nothing to iron or assemble on arrival. Machine wash cold, tumble dry low, and it is ready to wear again the next morning.
It reads as Celtic gear anywhere, but the palette points straight back to Glasgow, Scotland and Celtic Park.
