I’ve long ago given up worrying about looking like a prat. When I first started flying the Rans, I was flying with a former RAF fast jet pilot. He always wore his bone dome and suggested I get one myself.
The sound deadening is better than a conventional headset and it’s warmer in winter. It can get a bit hot in summer, but there again with our summers, it’s not usually a problem. It has accumulated a few scratches over the years, due to contact with the internal structure of the aeroplane, which might have made for a slightly sore head without it. Should I ever suffer the misfortune of ditching, it will keep my head warm and somewhat easier to see.
So no, I don’t worry about looking like a prat…
