Vikings did indeed have armour, they wouldn't run into battle naked tearing off someone's cuirass and donning a helmet mid-battle, and how do you think they got their funky helms? (Not talking about horned helms)

Chainmail wasn't efficient for them, because they sailed over seas, and heavy armour and deep water often isn't a good combo. They used shields, and if my research was correct, wore padded gambesons.
