I show how massless supergravity theories can evade the theorems that try to establish that there are "No Solitons without Horizons.'' The explicit construction of smooth, horizonless BPS solitons will be reviewed and some of their physical properties will be discussed. The possible role of such solitons in describing black-hole microstates will be examined.
