Evolution at work.

Whether you’re just looking to get started or you need to replace your daily-riding bibs and you don’t want to spend an arm and a leg, the Evoluzione 2 from Castelli is a great choice. Drawing inspiration from their top-of-the-line apparel, “entry-level” doesn’t do this bib justice. Featuring ProDry Soft 2-layer fabric throughout the front and rear panels for exceptional moisture wicking, a polyester inner layer is knitted with a nylon outer layer for a lightweight, durable fabric. The KISS Air chamois will keep you riding in comfort all day, just like it does for some of the pro riders putting in the miles at the Tour de France. Still think it’s just an entry-level bib?


  • Claimed weight: 177 grams.
  • ProDry Soft 2-layer fabric provides exceptional moisture wicking and durability.
  • Mesh bib straps.
  • KISS Air chamois.

Note: Castelli tops and bottoms are designed with a performance cut that often runs smaller than that of other manufacturers. Consider sizing-up one size to ensure a comfortable fit — e.g., if you normally wear a Medium, select a Large in Castelli. Feel free to contact us with any questions or concerns.

Excellent bibshort for the money

The Good, Sale Price $49.99, Got the bibs, threw them in the wash then took them for a 3 hour ride. Chamois is great, good size and padding, no issues at all the whole ride. Material is top notch with plenty of support and compression, not super thin nor to thick. All day comfort with these. The straps are nice and have good stitching on both sides all the way around, they should outlast the shorts. Styling, they're Castelli, very nice! The Bad. The sizing is definitely on the small side, I'm 5'7 I range from 155 racing to 170 off season, typically I can get away with most mediums, I ordered these in large because I know Castelli runs small, these were no exception. Currently I'm 170, These in large, on me are as tight as I would want any bibshort, also the straps are on the short side as I do not have a unusually long torso for being 5'7, most other larges the straps are to long but I have to buy to get the rest of the fit. Next, the leg band is nice with some silicon gripping in them but the band width is only 34 wide with extra stitching which causes a little too much compression right at the bottom of the legs. Yes, the length is a tad short but for 5'7 legs they work for me as I don't like them too long. As you get into the higher end bibshorts they've done away with this. Overall FOR THE MONEY at the sale price of $ I'll buy another pair for those short andor shitty day rides! I've been cycling for 30 plus years and don't think I've ever purchased a better pair for the $

Quality bib but short

Really like the quality and comfort. However, the legs are short and ride up. I may try another brand for a better length. Like so many have said this stuff fits tight so go up size.

Quality Castelli! I like the high rise in the front of the bibs (ride to drink more beer!), not the current low cut bib style. Medium size was spot on, 3-4-5 hour rides are fine in 100 degree temps. Time will tell if they will last more than a season with a nice rotation of my other bibs.

Great chamois. Odd sizing.

I ride 4 times a week with the club, 3short days and 50-70 miles on Sunday. The chamois never feels soaked. Best shorts Ive had for hot weather butt comfort. Im 61, 155, and wear a large. I know that now, after having bought a bunch of these. The new model has a sturdier bib section, and it seems to be no hotter than the old, cheese cloth mesh top. These shorts wear out first in the butt cleavage zone. They go into see through mode before they get baggy, or show other wear.

Way too tight. I normally wear large shorts. 190 lbs, 5'10. I went up to 2X after returning XL. Still like a cheap hotel.... you know the punchline. Made for the skinny youngsters.

Great bibs

I thought they might be a bit too tight when I tried them on. After my first ride I was sold! Fit is great, they stay quite cool, and the chamois is a delight. The logo on the thigh is wearing off as is one of the reflector hits. A bummer but still great bibs!
