  We present and discuss the results of the Giant Metrewave Radio Telescope
(GMRT) HI 21-cm line mapping for five isolated low-mass (M_bary ~(2--8)*10^7
Mo) eXtremely Metal Poor (XMP) dwarfs [12+log(O/H)=7.13-7.28], selected from
the Nearby Void Galaxy (NVG) sample. All the studied void dwarfs show the
disturbed morphology in the HI maps with the angular resolutions of ~11" to
~40". We examine the HI morphology and velocity field and the relative
orientation of their stellar and gas body spins. We discuss the overall
non-equilibrium state of their gas and the possible origin and evolution of the
studied void dwarfs. The most straightforward interpretation of the ubiquitous
phenomenon of the gas component non-equilibrium state in these and similar void
dwarfs is the cold accretion from the void filaments and/or minor mergers. The
cold gas accretion in voids could be linked to the presence of small filaments
that constitute the substructure of voids.
