The Helmet Visor Toggle Hotkeys for Toussaint Knight's Helmets mod for The Witcher 3 will allow you to swap between the two Toussaint Knight's helmet models with the press of a button. This mod does exactly that, as well as adding hotkeys for toggling your cloak and hood (credit to user anakmonyet for that part of the code!).

When you install this mod, you will be prompted to download an additional file that will be needed for it to work.

You also need to make sure that you have the latest version of the Mod.
