So I have an armor jacket (that is not good for summer).
An armor vest
Armor jeans
armor over pants (not good for summer)
and a helmet

And I'm about to get armor gloves.
But I'm thinking of adding more layers.
Like armor shorts, or armor shirt.
I feel like I'm one step away from adding a medieval shield. (or one of those airbag vests.)

How much protection is enough?
