We explore a class of dark matter models with two dark matter candidates, only one interacts with the SM sector. One of the dark matter is thermalized with the assistance of the other stable particle. While both stable particles contribute to the total relic density only one can elastically scatter with nucleis, thus effectively reducing the direct detection rate.
