Douglas P.wrote a review of Giordana Super Roubaix Leg Warmer on December 16, 2018
Familiarity: I've used it several times
Very warm and water resistant. Kept me comfortable down to well below 30 F. While not "water proof", they did bead water through light rain.
The only complaint is the rubber/elastic band at the top of the leg warmers. I suppose these bands are designed to keep them from slipping down your legs. However, when I've worn them under my bib shorts* for rides over 2 hours, the elastic/rubber ring rubbed through the top layer of my skin. Not the end of the world, but an ongoing irritation on long rides.
*Note: When riding alone, I wore the leg warmers over my bib shorts and there was no skin irritation. I've been told by more seasoned cyclists, that I'm supposed to wear them under my bib shorts lest I look even more like a Fred. Therefore, it's my vanity/lack of resistance to peer pressure that are perhaps the root of the problem...
If I had to choose again, I'd look for a set of leg warmers with a different mechanism to hold them in place.
