Is this a new trend?

Am sat outside waiting for my sons lesson to finish.

A group of (very polite) teenagers walk past. All the girls dressed for summer weather.

3 of the 4 lads had shorts, no tops on - but what caught my eye was that they were all wearing black balaclava type things. Is this a new thing? Are they supposed to be cooling or something?

I was surprised too. I'm wondering if security let it slide due the fact that they could be classed as a face mask? Some people are still wearing them.
