Fan gear that only works inside the stadium is not really fan gear. This Newcastle Staff Tee training jersey is cut to leave the stadium.
Fan-version build with the Newcastle Staff Tee colourway and Isak lettering applied front and back — the detail that separates it from a plain team tee. The colourway is matched to the on-field look rather than to a screen approximation. Sizing follows the US scale, so the letter size you normally wear is the right call.
It reads as Newcastle Staff Tee gear anywhere, on game day or off.
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.

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 the Newcastle Staff Tee name and number come already applied?
Yes. The jersey ships with Isak name and number already heat-sealed in place — no ironing or assembly on arrival.
