Whenever you have fresh-baked bread, let it cool completely before storing it in a plastic bag, ortherwise you’ll get moisture in the bag and the bread will absorb it & soften the crust.
Once I’ve cooled my bread, I cut a few slices and put a couple in a sandwich bag for easy access. I put the rest of the loaf in a bread bag and then suck all the excess air out with a straw before twist-tying it. Both bags go in the freezer. The couple slices thaw quickly for toast in the morning.
