unperturbable
Impossible to rattle
Unperturbable means impossible to disturb or agitate—calm under any circumstances.
The word is a less common variant of imperturbable, with the same meaning: She remained unperturbable despite the chaos around her.
Someone unperturbable maintains composure when others would lose theirs.
