I only wear PI shorts (Attack, I think). I've bought cheaper shorts but they just don't do, so I buy one pair of PIs every year and now I have lots (they last around 5 years for me)

Between 30F and 70F I wear my Sugoi winter tights over shorts. I would wear knickers in the 60-70F range if I had them, but I don't, so my Sugois are good.

Anything under 30F I wear my goretex pants over my shorts and winter tights. That's been fine down to 19F. It doesn't get much colder than that where I live.

I find leg warms uncomfortable, but that's just me.
