Aggie Pack Overview
The Aggie Pack is the easiest and best way for YOU to get involved at UC Davis.
The Aggie Pack is about the Students. It's about YOU. It's a place where everyone can come together to support one cause, the University of California, Davis. It is about students supporting other students. The Aggie Pack means more that just being a fan at a game. It means being part of the greatest University in California and doing it in way that is uplifting to the students, the campus, and the community. It is about showing the world what great students can do and what UC Davis is all about.
