Sono is a soft monospace (or proportional!) variable font. It has seven weights: ExtraLight through ExtraBold. The default style is fixed-width (and obviously not kerned), but thanks to the "mono" axis, you can add kerning and make the design proportional.

You can download font files directly and install them with Font Book. However, it’ll be much easier to install these fonts with RightFont — the best font manager for Mac.
