depending on temps, wind & precip I use a variety of things to get me thru to colder months
I start with Novara brand cycling pants
add generic running tights, under
remove tights under & add Showers Pass brand rain pants over the cycling pants (even if it's not raining)
ditch all that & wear just lined tech pants (Eddie Bauer brand)
some days I've worn EMS brand fleece pants, that I normally use as pajamas, w/ Showers Pass brand rain pants over
