Flying clothing
I am always totally amazed when I see pilots/passengers walking out to a light aircraft dressed in shorts and T-shirts. They would not be allowed on a car track day unless their legs and arms were covered.
If you want to learn more just read 'The Last Enemy' by Richard Hillary. Gloves are the most vital part of one's safety equipment. Nomex flying suits too are great.
So what do you wear? And do you carry a PLB? How much is your life worth?
All that said, when the OAT reaches 30 deg, as it did today, then I suppose you have to weigh up what is the greater risk: burning or dehydration.
At the end of the day, it is purely your choice.
