From the description: Chennai is a simplified sans-serif with a full complement of OpenType alternates. The characters are rounded, slightly extended and geometric. The OpenType alternates greatly complement the face. The primary version is more simplified, while the alternate is more traditional. These two “versions” are designed be used in conjunction with one another. For example, the primary version can be used for headings, while the alternate, with its stems and more traditional characters, can be used for highly legible body copy. Please see the PDF sample. Use Chennai whenever you need a contemporary and versatile sans serif.
