Okay then I suppose I'll simply leave it at that. I explained to you as for both anecdotal experiences, I have no interest in debating that, I say this is derived from a pair of LCD ear pads for example, and that answered your question as to which faired better. I don't challenge your claim of you feeling like leather is better, to which I also made closing comments in my first post saying, regardless of how better they are, it's not worth sending animals to death for it, and that's that.
Hopefully this quick summary explains somewhat to where you've gotten lost in the whole ordeal. But since you have no other interest than talking about proving some leather "breathes" or "ventilates" better, I have nothing more to say really. I explained even why that's lunacy since you're not going to be passing air through leather itself, but you also do not concede that either for whatever reason (you conflate with temperature vs air, to which i tried mentioning holds no barring on your prior claim's truth, yet you still are content with jumping from claim to claim).
Good luck to you, but this is all I have left to say.
