Lorica hamata / segmentata

[Tarbicus]

1. Blunt trauma.

Chain mail wearer is going to get a lot of blunt trauma compared to plate or "lorica segmentata" from hits. And padded undergarment might make it as hot as plate...and still not as resistant.

Chainmail makes the best protection on a motorbike apparently, and I did read there's a school of thought that, while mail is excellent against blunt trauma, it's only a secondary defence to the padded garment beneath it.
