Long, narrow hose-like tubes sized smaller than rigatoni but larger than mezzani. The addition of the word rigati (e.g. ziti rigati) denotes lines or ridges on the pasta's surface. Ziti are long hollow rods which are also smooth in texture and have square-cut edges; "cut ziti" are ziti cut into shorter tubes. There is also zitoni, which is a wider version of ziti.
