Subarmalis or gambeson?

[Nathan Ross]

Only complete Hauberk I know of is Arbeia and it did not have a leather edging.

I don't know of any fragments that do either. Several of the pieces from Dura Europos show edging of copper alloy rings (often all that remains, as the iron has rusted away), as does a fragment from a temple deposit in Oxfordshire, indicating that the practice was common across the Roman world. In the British case the edging rings were butted copper, suggesting a decorative function only. No indication that leather was attached.

Sculptural depictions of the 'shoulder yoke' style older hamata appears to show an edging on the shoulder flaps, but that's all I can think of.
