Kempe, of course, has skated internationally on plenty of occasions.
He's no stranger to the international stage, after all.
Kempe has taken spins with Sweden's gold medal entry at the World Under-17 Challenge in 2013, scoring one of his five goals at the tournament in the final.
He had three points (two goals, one assist), at the 2013 Ivan Hlinka Memorial, and was third in team scoring at the 2014 World Under-18 Championship, a fourth-place finish, too.
He added two appearances at the World Junior Championship, coming in 2015 and 2016. In 2015, he finished third in scoring with eight points (four goals, four assists), and second with eight points (three goals, five assists) in 2016.
But his latest experience easily trumps them all.
Understandably, it trumps any hockey experience he's had to date, in fact.
"For sure," said Kempe, who had 37 points (16 goals, 21 assists) in 81 games with the Kings - his first full season in the NHL.
"It's another level. You play against all the best players here, and you play with such good players as well. We had such a great team, too, in the tournament.
"Obviously it's the best thing that's ever happened."
He'll forever have proof.
"It's pretty heavy, so my neck is pretty sore right now," he said.
Chances are, he doesn't mind.
