Coach Kieran Crowley suggested earlier this week that Garbisi would be absent from his selection, but it appears the Montpellier number 10 has done enough to prove his fitness.
The squad has no real surprises in it, though Crowley is missing a number of injured players including number eight Toa Halafihi (29), hooker Gianmarco Lucchesi (22), fly half Leonardo Marin (20) and lock David Sisi (29).
"We have had a good week of work in Verona, putting the foundations in place for the Six Nations," Crowley said in a media release from the Italian Rugby Federation on Saturday.
"We are taking it step-by-step. Our focus now is on the present and that is France. We have faith in our abilities and are on our path with the aim of continuing to build something important."
Italy claimed a first Six Nations win in seven years when they defeated Wales 22-21 in Cardiff in their final game last season, ending a 36-game losing streak in the competition. They followed that up with a historic first victory over Australia in the autumn internationals.
They open their Six Nations campaign this year at home to France on February 5, before travelling to Twickenham to play England a week later.
