The Michigan Wolverines comprise 27 varsity sports teams at the University of Michigan. These teams compete in the NCAA's Division I and in the Big Ten Conference in all sports except women's water polo, which competes in the NCAA inter-divisional Collegiate Water Polo Association. Team colors are maize and blue, though these are different shades of "maize" and "blue" than those used by the university at large. The winged helmet is a recognized icon of Michigan Athletics.
