We explore the possibility that dark matter is a pair of vector-likefermionic $\mathrm{SU}(2)_{\rm L}$ doublets and propose a novel mechanism ofdark matter production that proceeds through the confinement of the weak sectorof the Standard Model. This confinement phase causes the Standard Modeldoublets and dark matter to confine into pions. The dark pions freeze-outbefore the weak sector deconfines and generate a relic abundance of darkmatter. We solve the Boltzmann equations for this scenario to determine thescale of confinement and constituent dark matter mass required to produce theobserved relic density. We determine which regions of this parameter spaceevade direct detection, collider bounds, and successfully produce the observedrelic density of dark matter. For a TeV scale pair of vector-like fermionic$\mathrm{SU}(2)_{\rm L}$ doublets, we find the weak confinement scale to be$\sim 700$ TeV.
