The font is actually not a revival of ‘Avant Garde’—by Herb Lubalin—but it takes its spirit. Fibra is a geometric sans serif, yet without the typical structural strictness of these kind of fonts, that represents experimental type design.
This can be seen in the contrast between curves and straight lines in some characters such as ’n’ and ‘h’ unlike rounded ones such as ‘a’ and ‘d’; details of some display characters (e.g. three upper terminals in ‘W’ and projection off the stem in ‘A’); and exaggerated terminal in ‘R’. All these features give Fibra a strong personality—a sans serif typeface that ‘gives you the chills’.
