  Multiple lattice evidences support the existence of a confining but chirally
symmetric regime of QCD above the chiral symmetry restoration crossover at Tch
~ 155 MeV. This regime is characterised by an approximate chiral spin symmetry
of the partition function, which is a symmetry of the colour charge and the
confining electric part of the QCD Lagrangian. It is traditionally believed
that confinement should automatically induce spontaneous breaking of chiral
symmetry, which would preclude the existence of a confining but chirally
symmetric regime of QCD at high temperatures. We employ a well-known solvable
quark model for QCD in 3+1 dimensions that is chirally symmetric and manifestly
confining and argue that while confinement indeed induces dynamical breaking of
chiral symmetry at T=0, a chiral restoration phase transition takes place at
some critical temperature Tch. Above this temperature, the spectrum of the
model consists of chirally symmetric hadrons with approximate chiral spin
symmetry.
