Something like this might be nice - but I don't know from experience:

I have these nice lined bib tights with stirrups - the ones I have are made by Giordana - I've had them for about 15 years... they've held up well! I tried to find some Giordana tights that are similar... but they are super pricey, at least what I've found.
I've had good luck with Pearl Izumi stuff too though, I've just never had any Pearl Izumi tights before.
