does anyone wear them?
Although made for men, yes I have. You need to be *very* secure with everything but it's comfortable once you become used to the idea that you are basically 'hanging out' under your doublet/surcoat. I like the heat dissipation.
I wear them. They were fine, but I wear them with maille and a surcoat.
I have tried to make a version for a female, and could not find a comfortable way to wear them.
