What's the best size for a layered NFL look?

NFL fan jerseys follow standard US sizing; most fans go one size up when they plan to layer over a hoodie.

Are the numbers stitched or printed?

Most fan-version NFL styles use printed, heat-sealed details — lightweight and tough, made to survive game after game.

Is this the same cut as the on-field jersey?

It's the fan version of the on-field look — the same team identity with a more relaxed, everyday cut instead of the pro locker-room fit.

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.

Make it yours today — pick your size, hit the checkout, and get ready for kickoff.
