In this Letter we show numerical existence of O(4) Dirac-Born-Infeld (DBI) Textures living in (N+1) dimensional spacetime. These defects are characterized by S N→S 3 mapping, generalizing the well-known Hopf fibration into π N(S 3), for all N>3. The nonlinear nature of DBI kinetic term provides stability against size perturbation and thus renders the defects having natural scale.
