Jeff wears Amfibs in the winter and loves 'em. I've never tried a pair but they sure do have nice features. I DO have a pair of the Thermafleece Cycling Tights, though. Thermafleece is the fleecy fabric used in the Amfibs. Then, the Amfib Tight adds another layer on the front of the windblocking, water-resistant fabric (the amfib fabric). Thermafleece is VERY nice and warm. I don't wear those tights over 55, and actually prefer it to be a bit cooler, like sub 50 before I wear them, otherwise I get a bit too warm.

So, yet another good option.
