They had either Wolf Shoulders/Bear Pelt when it had 16 body armour and 4 arm armour.Because a lot of people -- including me -- complained that Ulfhednars were objectively worse than the lower-tier troops they came from. And they were. That bare-chested with a two-hander look was stupid as hell both because it was maximum Hollywood and because they had zero protection from arrows.
If you're complaining about Sturgia's troops not having armor, it doesn't make sense to say Ulfhednars were any good.
Wold shoulder it was 12 and 3.
They had Bear Head(24 head armour) or wold head(12).
They had Decorated Mail Hauberk,now it's called Huscarl Decorated Mail.
It had over 30 body armour and over 10 periferies.
In total it had anywhere between 40 and 51 body armour,better than the Line Breaker.
