Some players change how a fan dresses on game day. Christian McCaffrey Vapor F.U.S.E. Stitched Jer is one of them, and this San Francisco 49ers alternate jersey is the short version of why.
This is the alternate build rather than match-worn kit: the same San Francisco 49ers look, a fan-weight mesh body, and a cut that layers over a tee. Sizes run men's S–3XL on the US scale.
It reads as San Francisco 49ers gear anywhere, but the palette points straight back to Santa Clara, California and Levi's Stadium.
Cut sits between slim and boxy, so it layers without looking oversized. The name and number are heat-sealed rather than printed on top.

Frequently asked questions
What if the jersey does not fit when it arrives?
You are covered by our 30-day hassle-free guarantee with zero restocking fees. If the fit is not ideal, contact our support team and your first size exchange is completely free.
What is the difference between this fan version and an on-field jersey?
This is fan apparel built for supporters: a lightweight mesh body and a relaxed cut, not the athletic cut worn by players on the field.
Does it work for Sunday watch-parties at home too?
Absolutely. The fabric reads as casual fan wear anywhere, not just inside the stadium.
What size San Francisco 49ers jersey should I order if I am between sizes?
US letter sizing runs true. If you want a relaxed layer for cold-weather games, take the size up; for a closer fit take the smaller one. The first size exchange is free either way.
