Linothorax vs Quilted linen vs spolas

[Braden Vande Plasse]

The main Gallic armour during that period is mail, and it was only worn by the elite. In many cultures body armour was only worn by the elite. The rest made do with a shield and, if they were lucky, a helmet.

There is a huge debate regarding overarm vs underarm. IMO overarm is more likely.

Haven't there been depictions of some Gallic tribes using tube and yolk armor? What sort of padding do you think the Gallic elite under their chain mail? It seems really stupid to not wear any padding, except in the Mediterranean where it could be forgivable.
