How well does your Thunderstroke handle the heat? Mine just purrs.
Believe it or not, a full face helmet in that kind of heat(dry) is far more comfortable than being directly exposed to it.Lucky on my bike the only thing that quits in the Kansas sun sometimes is my GPS display. Got my face and scalp a bit toasted awhile back because I lost my headgear part way through a long ride. No fun with eyes swollen and an allergic sunburn reaction that lasted for more than a week.
