Vanson properf pants advice sought

[Andrew Putnam]

Hi,
To those who have previously owned the Vanson properf fully perforated leather pants which I am thinking of buying a question for you if I may-
How well do these pants vent in summer riding? Here in Australia it's not uncommon in summer for temps to hit above 40C (105F approx).
I recently acquired the Vanson Cobra Mk2 size 48 which is pretty much a perfect fit. With the chest vents open this jacket vents very nicely through the chest and out the back vents while in motion. I can see this jacket being suitable for up to about 30-35C (85-95F) but beyond that I'm looking at getting a fully perforated model for Australian Summer riding.
As a comparison to the Cobra jacket I was hoping for some accounts of how effectively your perforated pants ventilated during high temperature riding and what would be their maximum wearable temperature.
Thanks for your help.

I rode with Vanson perforated sport rider pants and found them to be much-improved comfort-wise than nonperforated leather pants during hot days. I had pairs of Vanson pants both perforated and nonperforated. I also rode in Aero leather riding pants when I wanted to be more style-oriented
