Been up to 112 here recently; jeans, boots,full finger vented gloves, mesh jacket and full face helmet.
The full face checks the blast furnace effect and the jacket keeps the radiant heat from the skin while allowing air flow while moving. And in case one ends up laying on the 150+ degree asphalt keeps said skin intact.
That said, I don't think I'll ride to Death Valley in the Summer. It holds the record for hottest recorded temperature in the Western Hemisphere-134F (56.6C).
