Last year I bought Castelli Sorpasso Windstopper bib tights. I like them except when the temp is <40F, and I start feeling an ice pack against my crotch and lower abdomen! I wanted another bib with the Primary Goal to not freeze my tackle in temps into the 30’s. I tried on 5 sets of bibs tights. As long as you don’t wear these bare bottom and you keep the tags on, CC is great with taking back stuff you try on. I am 157lb, 5’ 7’’, 32" waist. My Castelli’s are a large, but I ordered M size for these 5 options: 1) CAPO PADRONE ROUBAIX: great look and fit, good compression, pad seemed very good, and more insulation in the lower abdomen/crotch area than the Soprasso. I also received a version with no zipper in the front as was shown on the CC and Capo websites (newer version). 3rd choice as I thought some of the other options had more insulation in the crotch/lower ab area. 2) GIORDANA FORMA RED CARBON WINDSTOPPER: Giordana has been my “go to” bib short for years. These had the most comfortable fit for me with no wrinkles, good compression, same excellent chamois as on their upper end shorts. They were the nicest looking bibs. I wanted these to be my choice, but I though the insulation in my “target area” would have been no better than the Castellis. 3) GORE OXYGEN WINDSTOPPER: from an insulation standpoint these would work well. Plenty of Windstopper fabric, and the chamois seemed fine. My biggest dislike was they were not very formfitting. Windstopper fabric does not stretch, so to make it work there need to be multiple panels, form fitting cuts, etc. These were baggy/wrinkly in the backside. There is no ankle zipper or footstrap, and I wondered if these would move around some on the ankle when pedaling. I could have worked with these but saw no point with the Xenon2.0 being only 10% more $$ and a much better design/fit. 4) SUGOI RS FIREWALL: their fabric felt stiffer and thicker than the Windstopper equipped bibs - not sure but maybe they would be warmer? They looked like they would have very good wind/cold protection, including the crotch and lower abdomen. Fit was very good, with very comfortable straps and a nice chamois. I liked the high cut in the abdomen and they had ankle zippers AND a small ankle strap that could be cut off. I tried these on the bike trainer. The ONLY complaint I had was that they seemed kind of tight in the calf area vs. the Xenons, which is really splitting hairs. GORE XENON 2.0: when I first tried them on I was really unsure. Pulling them on was the hardest because the hips were really tight, maybe because of the way the Windstopper fabric is cut. Once I got them over my hips and butt, they were comfortable. I was not sure about the combination of the thick footstrap (no ankle zipper) and the extra length of almost baggy fabric at the bottom. I love Gore winter clothes, so despite some quirks with my “dry fit” in the dressing room, I thought these might be the best choice. I tried them on a trainer and the ankle fabric tended to even out and was no concern for me, even though I am on the short end of the spectrum. Ultimately I thought the way they cut in the windprotecting fabric was a little better for me compared to the Sugoi, and the fit was more comfortable sitting on a trainer. I have ridden once in the mid 40’s, and once at around 35F with a little breeze. I really like them! The chamois and shoulder straps are awesome, fit is great and they have good compression. They are totally warm and insulated in the target crotch and lower ab area. There is a section of non-Windstopper fabric cut in a diagonal wrap across the thighs to provide stretch that you feel in colder temps. It’s more of a temp difference from the Windstopper protected area and not really cold. Once I warmed up that feeling went away. I'm still not crazy about the thick ankle strap, but otherwise extremely happy with this choice. Give them and the Sugoi a chance.
