Quilted armor? Helmets?

[Dan Howard]

Is the Crocodile skin "Armour" a religious/festival costume or Burial rite connected with Sobek who was still revered in Ptolomaic Egypt?

This is very unlikely to be armour; it is completely open down the front.You'd need to spend all of your time with your back to the enemy to get any kind of protection from it. It is more likely some kind of religious costume. In any case, crocodile hide makes lousy armour. It would need to be a lot thicker than this costume to stop spears and arrows.
