Castelli Sorpasso 2 Bib Tights Review

The Sorpasso 2’s are classic Castelli cold-weather bib tights.

Sorpasso 2: your cold-weather companions

Staying warm at speed while not overheating is a tough challenge for winter-weight bibtights. Not all can handle it, but those white whales that do can make winter riding a delight. Winter not only means cold, but occasional precipitation — rain or snow, depending on where you are. And, it’s impossible to forget about the wind chill at speed, which quickly separates the imposters from the real thing.

When it comes to cold-weather riding gear, there’s no doubt that Castelli comes to mind as one who has mastered the art of year-round riding. For years, their unbranded fabrics were by non-Castelli pro teams until their apparel makers could make something comparable.

All those scorpions, keeping me warm and toasty for some gravel adventures.

With the latest Castelli Sorpasso 2 bib tights, we’re talking about cold-weather protection at its finest. When I say cold weather, I’m talking about temperatures in the 35-50 degree range. For me, road biking in the upper 30’s is the threshold for before I elect to just ride indoors. On the MTB, I’m good down to 30-degrees due to the lower overall speeds. The Sorpasso 2’s are just right all the way down to my personal thresholds of comfort.

Castelli uses a mixture of Thermoflex Core2 and Thermoflex fabrics to keep the elements at bay. This fleece-backed fabric does an excellent job of blocking chilling winds and keeping muscles happy. In the cold, muscles need warmth and compression and the Sorpasso 2’s deliver that quite well.

Don’t let the blue skies fool you, this was one cold day on the bike.

Often, winter-weight bibs can inhibit movement, but these are only minimally-restrictive and among the best I’ve tested. As with all Castelli bibs, the size large are a snug fit on my 5’11” – 170 lb. body. A little bit of wiggling and the flexible, wide straps keep everything in place (and comfortable). With such an excellent fit, the only downside comes when it’s time to use the bathroom as they don’t stretch well enough for proper relief without resulting to contortions.

With the Progetto X2 Air chamois, you can expect excellent saddle comfort on both long and short rides alike. It’s a spectacular chamois that matches quite well here — even though winter rides tend to be on the short side. When temperatures get warmer, the Termoflex panels do breathe, will get toasty on long efforts when temperatures get into the low 50’s.

On the warmer side, the Sorpasso 2’s remained comfortable into the upper-40’s.

While these remain an awesome choice for cold-weather riding, they would be over-the-top with a little water resistance. Frankly, I’m surprised that the front panels don’t offer water protection, but you can’t always have it all.

Lastly, I’ll mention that the leg zippers are well-placed and make things easy to both put them on and take them off. And, the zippers remain unnoticed while pedaling (something that’s not always the case with winter bibs).

The Good

  • Comfortable, fleece-backed fabrics
  • Keeps the wind at bay — even at high speeds
  • Great compression to keep muscles happy
  • Upper straps are flexible, wide and comfortable next-to-skin
  • Breathable mesh in back helps moisture escape

The Bad

  • A little DWR treatment would be nice
  • Good luck going to the bathroom

The Bottom Line Castelli Sorpasso 2 Bib Tights

Heading out in the cold requires the proper equipment and you can’t go wrong with Castelli head-to-toe. The latest Sorpasso 2’s are excellent for cold-weather riding from 35-50 degrees with soft, fleece-backed Thermoflex fabric throughout.
