[Closed] Knee warmers. Are any of them any good?

Has anyone found any knee warmers which are comfy and stay in place?

I've not got a huge commute, so I just wear casual shorts. The knees are getting a bit chilly recently, as they would.

I don't want to wear trousers, so I've been looking at 3/4 tights.

I still don't need padding, though, so what about the knee warmers.

Anyone use them, or are they too much faff?
