Subarmalis for lorica hamata

[Primvs Pavlvs]

I seem to remember reading a reference to soldiers wearing Corsican leather, but I cannot seem to remember where I read this. Either way I think leather, or cloth would have been used since the Romans seem to have made many objects from leather why not a subarmalis?

We cant let our modern concepts of whats comfortable, or practical for clothing get in the way. Clothing from a meer 60 years ago is considered uncomfortable to many with our modern concepts of what is comfortable.
