"You are currently wearing more than one face covering"

[Mathias]

What other worn items, especially head armors, do you have?


The security armor helmets are tagged differently in HL from a standard helmet - presumably the standard "helmet" is just a motorcycle helmet or batting helmet type of thing, and can be combined with respirators, filter masks, ballistic masks, and other face/mouth covering items, but based on the descriptions, the security armor helmets seem to always be face-covering, so they're set up to conflict with items like that.
