Anything under there is going to be soaked with sweat.

Nomex vs CarbonX.

The idea of CarbonX is that it is heat resistant. Found this on their website:
CarbonX heat resistant clothing offers the best level of fire and heat protection in fire resistant clothing in the most extreme conditions. Based on patented blends of oxidized fibers, CarbonX is the only fabric able to withstand the direct flame of a blow torch without melting, igniting, or burning—even when exposed to the flame for up to 20 times longer than the leading competition.
At the PRI show, they demonstrate with a small blow torch and the guy's hand on the other side. The heat doesn't come through and burn his hand. All while the Nomex melts.
