How do NBA jersey sizes run?

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

Is this jersey unisex?

Yes, the cut works for everyone — most fans simply choose their usual size. Women may prefer sizing down for a closer fit.

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.

Add it to your cart and wear your colors with pride this season.
