Linothorax vs Quilted linen vs spolas

[PMBardunias]

Ruben, great find! This dovetails nicely with Aeneas Tacticus 29.1-4 which you posted a while back if we assume "stolidia" reads "leather armor":

...accomplices there were brought in linen corslets [thorakes lineoi], cloaks [stolidia]...

The concurrent use of both leather and linen is a nice place for this debate to end up. I do wonder if Stolidia/Spolidia and Thorakes describe modes of construction rather than material. Perhaps Spolidia is synonymous with a Tube and Yoke, for it hangs like an apron or the skin of an animal (a la Heracles as Christian noted) and is "short" for a garment, while Thorakes is more general and broad sensed or may imply a vest cut?

Note that the Pilos were textile:
