Leather or linen pteriges?

[Tita Iuventia Martia]

Salvete omnes,
Linen or leather pteriges? What is your personal opinion?

Well, I think that the linen one is more correct than the leather. Here are my arguments, why:
- because its origin in the linen stripes on the Greek armor (Linotorax)
- we can see a white stripes on the mosaics (forinstance in The book Praetorian guard by Boris rankov)
- linen fabric is more comfortable than leather and also lighter to wear
Yes, I know that this arguments are only my personal guesswork, because we have not so much of the evidences about the subarmalis and the pteriges (nothing survived). We know that Romans probably wore some pedding under an armor (we can see it in the reliephs, mosaics, tomb stones etc.) but we are not sure, how the subarmalis looked and designed. Modern reconstructions are only our guesswork. So, no doubt that Romans used a pedding under their armorrs. But from leather or linen...
What is your oppinion about this theme?

Thank you for your answers and regards :-) )
