Linothorax again

[hoplite14gr]

Dan´s friend has a very strong argument. And his post prompted me to try and check and if possible verify the idea.
An aunt of my wife worked in a factrory of ex-Soviet Union making staff for the once mighty red army. She told us (my wife kindly translated) that if they wanted to create extra strong material for various functions they used layers of material at 45 degree angles not only in linen but in camvas (hessian) too.
The lady also claimed that angling layers aid waterproofing.
Well I am not a clothing expert so can't strongly support all that but I think they knew what they were doing these days.
Kind regards
