  GeV-scale dark matter particles with strong coupling to baryons evade the
standard direct detection limits as they are efficiently stopped in the
overburden and, consequently, are not able to reach the underground detectors.
On the other hand, it has been shown that it is possible to probe this
parameter space taking into account the flux of dark matter particles boosted
by interactions with cosmic rays. We revisit these bounds paying particular
attention to interactions of the relativistic dark matter particles in the
Earth's crust. The effects of nuclear form factors, inelastic scattering and
extra dependence of the cross section on transferred momentum (e.g., due to
presence of light mediators) are studied and are found to be crucial for
answering the question as to whether the window for GeV-scale strongly
interacting dark matter is closed or not.
