Mislab from Typofonderie
Ariadne Remoundakis, writing for Typekit:
Designed by Xavier Dupré, Mislab succeeds in its role as a robust display face while also maintaining delicate features. Though the uppercase letters maintain strong serifs, most of the lowercase letters — notably the a, c, e and s — are left with sans serif endings. Even the x, a perfect candidate for symmetrical slabs, is treated in a fluid way with one of the terminals ending in a curve.
