I have Mjoll the Lioness as my follower. While she does wear any armor I give her initially, she always puts on her Banded Iron Armor again after I change areas or fast travel.

I have attempted multiple mods and methods (such as pickpocketing) to keep her from putting on the Banded Iron Armor, but she always spawns a new one and puts it on.

Has anyone been able to figure out a way around this at all? Lydia wears what I want her to as well as other housecarls, but Mjoll and other unique companions, like Cicero or Uthgerd, constantly wear armor they have on default despite all of my various attempts.

This irritates the hell out of me, I wish Beth would just let us remove everything they have, then we can choose what items we give them. The only item they should have 'hidden' is an unlimited supply of iron arrows for archer followers, but they will equip better arrows if you give it to them.

I assume this is purely aesthetic? Mjoll can't die so it doesn't matter what armor you give her, I think the banded iron looks pretty badass on her ha.
