Regardless, the main current path in a Faraday suit is through the chain link, not the person. However, the very nature of chain mail is that it has many individual connections, dynamic impedance, and is in physical contact with your skin in many different places. This almost certainly results in your body being in parallel with the chainmail conductor at several points. Of course, your body has a very high impedance compared to the chain mail, so it will carry a much smaller current than the chain mail. In summary, the chainmail acts as low impedance path to ground for current to flow.
