Sorry for the delay Ken, I haven't had much time to check the forum lately.
My wife tried out a pair and like them. But knowing that she get's cold very easy (and she did get cold wearing these on a chilly ride) I don't have a real good gauge yet on how they perform over standard thermals.
Riding season is over here in the Northeast (salty roads) so I may not get a chance to try them myself until spring.
Wish I could be more help.
