  We study the temperature dependence of the renormalized Polyakov loop in 2+1
flavor QCD for temperatures T<210 MeV. We extend previous calculations by the
HotQCD collaboration using the highly improved staggered quark action and
perform a continuum extrapolation of the renormalized Polyakov loop. We compare
the lattice results with the prediction of non-interacting static-light hadron
resonance gas, which describes the temperature dependence of the renormalized
Polyakov loop up to T<140 MeV but fails above that temperature. Furthermore, we
discuss the temperature dependence of the light and strange quark condensates.
