If you leave bread fully enclosed in plastic, all the moisture from the crumb moves into the crust and makes it soggy. But it doesn’t dry out.
If you leave it just open, it dries out.
That’s why (real) bread is best stored in a paper bag or in an unglazed ceramic bread bin. Those two materials allow for a slow exchange of air, therefore keeping the crust crunchy and the crumb soft.
