Abstract
Spontaneous compactification is shown to predict a novel type of localized four-dimensional horizon-free objects. These are cores of scalar fields confined by means of a static domain wall. Their surface area is at most frac94; the area of an equal-mass black hole. Altogether, they make excellent candidates for Einstein's gravitational bags.
