  Assuming that the Hagedorn fluid composed of known particles and resonances
with masses $m<2\,$GeV obeys the {\it first-order} theory (Eckart) of
relativistic fluid, we discuss the transport properties of QCD confined phase.
Based on the relativistic kinetic theory formulated under the relaxation time
approximation, expressions for bulk and shear viscosity in thermal medium are
derived. The relaxation time in the Hagedorn dynamical fluid exclusively takes
into account the decay and eventually van der Waals processes. We comment on
the {\it in-medium} thermal effects on bulk and shear viscosities and averaged
relaxation time with and without the excluded-volume approach. As an
application of these results, we suggest the dynamics of heavy-ion collisions,
non-equlibrium thermodynamics and the cosmological models, which require thermo
and hydrodynamics equations of state.
