I am a Giordana fan as their clothing fits me the best and their chamois is super comfortable. I have FRC Wind bib tights, which are most excellent, but I thought I would try these as an in between.
First, the quality is great. This is a well made pair of tights that will last a long time.
But . . . These did not fit my needs, but they might fit yours. I tried them, and they are not windproof enough for me, nor do they have enough insulation. They bead water well, but your legs will get very chilled in a rainstorm.
If you are warm blooded, they would be fine for the 40's, but they are not for me. They would be fine for 50º and rainy for me, but 50ºF temps, I would just wear knickers and long socks.
I found the insulation was not thick enough, and I would have preferred the protection of the FRC wind bib tights in rainy 40º something weather.
I wear a Large in my other Giordana FRC tights, and these tights seemed a little bit less compressive than my FRC tights and a tad roomier. I am curious to know if the sizing is the same in this round of updates or if the newer garments are a bit roomier than their predecessors. You might not need to size up in these.
I also don't like that they did not use paneled construction—they just aren't as snug and comfy. They do this to cut down on seams that would allow water inside, but you lose comfort and compressive support.
I also found the chamois to not be as comfortable as the FRC. I think part of the issue is that the garment was not compressive enough, which might allow the chamois to move around a little more.
I would be curious to try the AV bib tights to see if they are more compressive.
So, these tights might work for you or they might not. If you are looking for something super burly, just go with the AV bib tights instead.
