In addition to being a solution to the little hierarchy problem, the Mirror\nTwin Higgs provides a natural setting for Asymmetric Dark Matter. In its\nincarnation with only one Higgs doublet and its mirror copy, dark matter would\nhowever almost certainly consist mostly of mirror atoms, which is severely\nruled out by constraints on dark matter self-interactions. By adding a second\nHiggs doublet and its mirror, the vevs of the different Higgses can be arranged\nsuch that dark matter consists mostly of mirror neutrons, which is\ncosmologically viable. In this paper, it is shown that current constraints from\ncolliders, flavour and cosmology can accommodate such a vev structure with\nlittle increase in the necessary tuning.\n
