Subarmalis for lorica hamata

[SOCL]

Fellows,

I should be receiving my lorica hamata in mid to late December from Find-It Armoury (my first armor! what is recommended? I am especially looking for responses from those who have worn or wear hamata on a regular basis.

Next order of business is the material and colour. If I understand correctly, the cloth itself can basically be of any colour since the subarmalis would likely have been made of old, rather useless material (such as an old tunica). I'm not so much concerned about that as I am about whether it should be cloth or leather. If leather, which is what I am leaning towards, can anyone give me or direct me to any examples of leather subarmalis period appropriate (i.e. late Republican-early Imperial)? Further, would this be rather along the same lines as ones worn by centuriones, but with less "wow" to them, or is there a "pattern" much more simple?

Thanks!
