inefectivity of leather vs thrusts is very well known, its not ideal thing to have if enemy is using thrusting weapons... If I remember right, you can pierce through boiled leather with just 30 joules of energy (Dr Alan Williams tests) so in the times where everybody was using thrusting spears, I would really not want to use a leather (or more likely rawhide) breastplate...
