Armour against weapons or weather?

[Giannis K. Hoplite]

To me both look more like the chiton itself,without even another garment beneath it.Look in the famous vase with the hoplites arming up,for example.(Greek Hoplite p55)Some of the warrior wear ecactly the same garment,but the pleats are visible and show it's clearly a light chiton.
The second one is an even more crude depiction of a chiton,the painter's "mistake" is that he didn't do any pleats in the upper part,but anyway,even the lower curves and pleats can not be compared with the other vase!
So what is that cloth arrownd his waist?In my opinion it's an ephaptis.This was usually worn with nothing else but could also be worn over a chiton.(see Greek Hoplite p54,and plates B and F)
The double line in the edge does not indicate multilayered garment.It is just the hem line,also depicted in numerus vases.Don't change book,see examples on p.61 and plate D.
Just my opinion
