(Just in case anybody doesn’t know what a Balaclava helmet is, see here.)
When I was a kid, every boy had one. (Girls didn’t, for some reason; maybe it was because their hair was longer and they had less need of one.) But then they became associated with nerdy types and fell out of fashion, which is an awful shame because they were a very practical bit of kit. I haven’t seen a kid wearing a Balaclava for many years.
If I were a celebrity, I’d start wearing one just to get the fashion going again. But I’m not. If I wore one now, people would roll their eyes and put it down to my strangeness. Besides, I wouldn’t know where to get one. Mothers used to knit them in my day, but times have changed.
