I think chain mail armour is more likely than leather armour. Númenór was basically the pinnacle of technology in Middle-Earth. They would have metal armour made strong but also light. Besides, they are so confident as to challenge Sauron and invade Valinor. There is no way they would try that with leather armour. Their main “battles” are on land, so they would probably don their armour when they got to shore if they were worried about drowning.
