In this talk, I will discuss various aspects of spin superfluidity (long-ranged, dissipationless transport of spin angular momentum) in magnetic insulators that make it distinct from the familiar mass and charge super fluids. I first propose the simplest realization of the phenomenon using a spin Hallfacilitated two-terminal device. Various U (1)-symmetry breaking effects that lead to the suppression and the eventual destruction of the superfluid state are introduced and discussed. I then present ways in which superfluid-like behavior can be restored in the presence of such detrimental effects by considering spin transport in the AC regime and via topological magnetic solitons.
