I've been looking for almost an hour now, and I can't find it in my construction set. FCOM is the only major mod I have installed.

Didn't mean to add helmet in the title, it just adds a colovian cuirass and a shield.

It looks just like any other light armor guard uniform, except it's heavy armor. And it's white just like Kvatch.

It's from MMM. Also next time you could try using FormID Finder or RefScope to find out which mod an item is from.

FormID is a mod right? That would save me a lot of stress, but I don't wanna add any more mods.

And thanks BTW.

FormID Finder is a mod, but it's of the sort where there's about a 0.00000001% chance of it conflicting with anything or causing any problems.
