From http://andrewpaglinawan.com/category/typefaces/#quicksand:
Quicksand is a sans serif type family of three weights plus matching
obliques and a dash version for display and headings. Influenced by
the geometric-style sans serif faces that were popular during the
1920s and 30s, the fonts are based on geometric forms that have been
optically corrected for better legibility.
