Men's Boston Celtics Jayson Tatum Kelly Green Big & Tall Fast Break Player Jersey - Icon Edition
Size Guide
Everything below is the garment measured flat, not your body. Chest is the full width from armpit seam to armpit seam; length runs from the highest shoulder point down to the hem. Fastest way to get it right: take a jersey that fits you well, measure it the same way, and match the numbers.

Authentic - Numbered Sizing
36 - 64Some Authentic styles are sold by number instead of letter. The number is the chest width in inches - so a size 48 measures 48 in across. Use the letter column to translate your usual size.

|---|---|---|---|---|---|
| 36 | XS | 36 | 29 | 91 | 74 |

Basketball jerseys are meant to hang loose. If you want a regular, closer fit, order one size below your usual.
Go up. The extra room is how the cut is designed to be worn, and it layers over a hoodie in winter without pulling.
Match the numbers to a shirt you already own rather than to your body. Printed names and numbers on the back do not change the fit.

Description
A Boston Celtics jersey with Jayson Tatum on the back, comfortable enough to forget you have it on.
It is the sort of jersey that stops being special and starts being normal — which is the point. It reads as Boston Celtics from across the room and as Jayson Tatum up close. The name, number and chest marks are sealed on in layers, which is why the edges feel crisp rather than flat.
Recycled polyester, wicking finish, and a knit dense enough to hold its shape but light enough to forget. A tagless V-neck with taped back neck keeps the inside smooth — no label, no irritation. Between the colour, the cut and the lettering, it covers casual Fridays and playoff nights equally well. It layers under a hoodie without bunching at the shoulders. It arrives ready to wear — no odd smell, no stiff finish, no first-wash surprise.

Pressed, folded and ready to wear — there is no assembly or first-wash ritual.
Can it be worn as everyday wear?
That is what most people end up doing with it — it works as a shirt, not just as a jersey.
