Open up this mod's XComContent.ini and put a ; in front of those items you don't want.

The names of the archetypes in the XcomContent.ini file might be a little cryptic, to easily identify them have a look at the XcomGame.int file (in the Localization folder of the mod). Then once you have identified the item you don't want a appear in game replace the + by a ; at the beginning of the corresponding item's line.

A word of advise however: altering the mod files if you don't have some experience in Unreal engine coding is at your own risk.

I have done this just fine and it works.

I disabled all the Bandanas/Headbands/Masks/Shemaghs/Ballcaps as i didnt like them as dont think they fit the game.

Infact i would actually prefer a separate mod that only adds the torso/arms/legs/helmets and none of the others so that when the mods updated i dont need to keep editing the ini file to disable the bits i dont think fit, and this way they dont show up randomly in game on soldiers.

Is that the only way of doing it? There are some things I would like, but there's also a lot of things I don't want and I don't want them to take up space unneccesarily.
