I have done only a few flights above 13K' MSL in the east, never higher than that.
In other parts, 13K' MSL is a decent Soaring day.

So, I am NOT an expert!

Yes, metal rudder pedals can suck heat real fast.
Sunlight can help a lot.
Being damp (rigging, damp day, whatever.....) REALLY sucks heat.

I can only go by many years/miles hiking and likely lower flight altitudes for flying.
I will TOTALLY defer to others that think my "great altitude" is sorta the bottom of their "safe altitude".

Gotta think of where you are vs. where info is coming from.

Actually Dan, while wool is a great material for fabric, in technical uses it has been replaced by new technical fibers and will not absorb any water. I basically flying sailing clothes. Including wave flights in by leather sailing boots.
