Is it ok for men to wear tights under their trousers in cold weather?

Yes !

Couldn't you purchase some thermal underwear? Marks and Spencer have a fantastic range for sale at the moment.

Does anybody else have any views on this?

Just hope you don't have an accident that requires you to have your trousers removed, could make for an awkward moment all round

They are prone to ladders, I prefer to just keep my lounge pants on under my trousers.

seems fine to me. I recall being in the Air Training Corps and being advised by the NCO's that the best thing to wear under combats at night in winter were tights.

If men want to wear tights then why shouldn't they? Whether it's for warmth,to help circulation problems,because they just like wearing them or any other reason,it's not harming anyone and there's nothing wrong with it. And yes,I wear them myself and I have a pair on now.

A well-known trick of the trade used by builders and other outside workers. I personally prefer long running leggings or long-johns worn over my underpants and under my trousers so I am triple-bagged in the vital area.

Sure why not! I was always under the impression that they were originally mens wear anyway

sure! why not?

That should be fine i believe for any gender class

of course sure....no doubt...

Jockeys wear tights under their breeches.
Judges wear tights under their robes.

I don't see why men shouldn't wear tights. I suspect stockings sales may go up instead though....not sure if for the kinky factor or the comfort one though.
