Make hats actually make sense.

[Camnui]

Hat items shouldn't prevent strangling/changeling-grabbing/vampire biting, there's no logical reason they should. Helmets, facemasks and such are fine, but some silly hat that would provide no protection at all really shouldn't prevent a horrible demise, there is currently no reason to not wear a hat, and the only antag with a reliable way to remove them is the ling, all others have to spend around 30 seconds or so removing a hat, then a mask, when realistically speaking it would only take a couple seconds to remove a hat or even just ignore it.
