my legs feel like sludge in cold temperatures, but I went cheap last winter and was wearing only the nashbar tights and they are horrible! I've become very acclimated to cold weather living in ohio and I was still FREEZING with those things. I have to come up with another alternative to those for this winter that should be coming up soon, any suggestions? I have a sweet PI jacket that keeps my upper body warm, just my legs were so cold.
