In this talk, I will discuss the freeze-in dark matter  production mechanism at low reheating temperatures. The process is  Boltzmann-suppressed if the dark matter mass is above the reheating  temperature, and, in this case, the coupling to the thermal bath has to  be significant to account for the observed dark matter relic density. As  a result, the direct DM detection experiments can already probe such  freeze-in models, excluding significant parts of parameter space. The  forthcoming experiments will explore this framework further, extending  to lower couplings and higher reheating temperatures.
