I've been working on a usable sans serif for body copy since the mid-1990s (though I certainly did not know it at the time).

This one works well. It started life back in the mists of time as an old Dutch Bible font. It was developed fully as a synergized serif with strong traditional roots and released as Bergsland Pro.

Now it finally makes it to where I was headed all along as a sans text font. This is a well modulated humanist, sans serif font family with many OpenType features and over 600 characters: Caps, lower case, small caps, ligatures, swashes, small cap figures, old style figures, numerators, denominators, accents characters, ordinal numbers, and so on.

It is designed for text use in body copy. But it also works very well for elegantly stylized display.
