Euclid Flex is a geometric sans-serif typeface released by Swiss Typefaces in 2013. It has an impressive five weights available with matching italics. And each weight of Euclid Flex contains more than 500 alternate characters and ligatures, making it an extremely flexible family. I love the quirky curves in the lowercase f and g.
