How do NBA jersey sizes run?

Standard US athletic sizing. If you're between sizes, sizing up gives a looser, on-court-inspired vibe.

Are the numbers sewn or printed?

The markings are printed and finished to look clean and hold up over time. It's the standard for fan-version jerseys at this price point.

Will the print or numbers fade or crack?

The markings are finished to hold up through normal wear and washing. Wash cold, inside out, and avoid ironing directly on printed areas to keep them sharp.

Does it come in other colors?

This product page shows one colorway, but the team's home, away, and third looks are available across the store — check the collection for more options.

Your spot in the stands is ready — grab this Boston Celtics jersey before your size is gone.
