03
A Fit for Real FansDesigned to follow the natural line of the body while keeping the relaxed, game-ready feel of a fan jersey.
04
Built to Hold UpClean team markings, tidy stitching at the seams, and a collar that holds its shape wash after wash.
This San Francisco 49ers 2025 Rivalries Collection Game Jersey from is an ode to a fanbase that moves more like family. The authentic-style look features an all-black design with classic saloon-style numbers and gold accents representing the franchise's storied legacy.

Wear It

Whether it's Father's Day, a graduation, or just a 'thanks for being a fan' — this one lands.

The Details

  • Fit: women's sizing; check the size chart for exact chest measurements.

True to size for most fans; if you prefer a looser, game-day layering fit, consider going one size up.

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.

Can I iron the jersey?

If needed, iron on low heat from the inside and avoid printed areas. Steaming is an even safer option to smooth out wrinkles.

Can I buy multiple sizes to compare?

You can place separate orders, but we recommend checking the size chart first — most fans land it right the first time.

How do I choose the right size?

Check the size chart on the product page — chest width is the best guide. When in doubt, most fans size up for a relaxed, game-day fit.

Show up, stand out, cheer loud — this San Francisco 49Ers jersey is one click away.
