I just got me these tights which are very warm, down to 10 F, if you put a capilene underlayer.
Hint: pick the one with the SMOOTH OUT feature, it's warmer and suitable for cycling. Call Franziska if you want the Navy color, which for some reason is not shown/liested in the internet order feature.
compare with Coldlizard's one which it's more expensive:
Thought I share onthis great deal!
