Confining dark sectors provide with an appealing candidate for the Dark Matter. In this talk, I will focus on the rich phenomenology of these models that has drastic implications for their detection prospects and relic abundance calculation. On the detection front, I will show that a broad class of vectorlike confining dark sectors are endowed with a symmetry (H-parity) that suppresses their signals at direct detection experiments. On the abundance front I argue that in the heavy quark limit the confinement phase transition depletes the symmetric component of dark matter abundance by orders of magnitude - independent of the portal to SM. I will also show that, based on basic group theory argument, in minimal vectorlike confining dark sectors is typically a singlet of SM. Combined together, our results identify glaring gaps in our experimental program that can only be filled by future collider searches.
