We study the theory of a (global) texture with DBI-like Lagrangian, the higher-dimensional generalization of the previously known chiral Born-Infeld theory. This model evades Derrick's theorem and enables the existence of solitonic solutions in arbitrary (N+1) dimensions. We explicitly show the solutions in spherically symmetric ansatz. These are examples of extended topological solitons. We then investigate the coupling of this theory to gravity, and obtain the static self-gravitating solitonic p-brane solutions. These nonsingular branes can be identified as the smooth versions of cosmic p-branes which, in the thin-wall limit, suffers from naked singularities.
