My first flying instructor (ex-military who taught me on an air cadet flying scholarship) told me that he used to fly with the bottom of his flying suit sleeves rolled up and the cuffs on his flying gloves rolled down. He had badly scarring around his wrists where he had been burned by a flash fire in the cockpit (Canberra I believe). He used his past injuries to explain why it was not a good idea to fly a Cessna 150 while wearing a short sleeved T-shirt. After that I always flew with gloves whenever practical - even as mission crew in the back of large aircraft.
