Thermal pressure alone may not sustain a large scale outflow in low mass galaxies (i.e $M\\sim 10^8$~M$_\\odot$), in the presence of supernovae (SNe) feedback with large mass loading. We show that inclusion of cosmic ray pressure allows outflow solutions even in these galaxies. In massive galaxies for the same energy efficiency, cosmic ray driven winds can propagate to larger distances compared to pure thermally driven winds.
