A vanilla friendly "Brigandine"-Armor.
Steel Armor Replacer or Standalone version.

Hey There!

This is my result after trying to create some kind of a Brigandine-Armor by only using vanilla textures and meshes.
It`s simply a fusion of the stormcloak and dawnguard cuirass - for male and female

Now you can wear a very vanillafriendly "Brigandine"-Armor without being referenced to the dawnguard.

There are two versions:
Replacer: Replaces the vanilla steel armor.
Standalone: Adds a Standalone version to the game, which can be craftet at the forge. The stats are the same as the vanilla steel armor.
