Sugoi is famous for packing loads of useful technology into its consistently affordable offerings. Evolution bib shorts are a perfect example of how Sugoi earned this reputation. The Evolution has been evolving for years, and this latest edition is the best yet.

The Evolution bibs made their name by being more than just a comfortable chamois supported by breathable fabrics. This latest generation of the bibs employs the latest version of Sugoi's EvoPlus fabric, a highly stretchable polyester and spandex blend that also provides a compressive effect for supporting the muscles and fighting their fatigue. No fewer than eight fabric panels, combined with flatlock seams, serve up a precise and incredibly comfortable fit. Inside, the excellent RC Pro chamois can still be found, which balances the jobs of evacuating moisture from your skin while also supporting your sit bones and relieving your soft tissue of the unneeded pressure that can ruin longer rides.

  • A comfortable, budget-friendly bib short
  • Stretchy, supportive fabrics provide comfort over long miles
  • Moisture-wicking chamois protects without excess bulk
  • Powerband leg grippers comfortably hold hems in place

low durability

  • Size Bought: medium

I purchased these bibs exactly 63 days ago. I have worn them about once a week for road rides from 20-60 miles using chamois cream. I purchased them to replace old bibs that I had worn for the same purpose for the previous 4 years and decided its probably time to replace. First, they don't show you a picture of the chamois, but it has two seems on the front of the chamois. I was concerned this would cause problems with rubbing, but actually it didn't. The bibs were very comfortable, fit appropriately, and did not cause any rubbing, chafing, or sores. So the second part is that now, about 8-9 weeks after purchasing, the seams on the chamois are pulling apart and these bibs likely wont be wearable in a few more rides when your junk tries to pop into the nice little pouch that has been created between the chamois and the outer material. Additionally there is slight texture on the outside of the bibs that has started to pill up from where my leg rubs the saddle. So, given that my previous bibs lasted 4 years and are still in one piece, I am quite disappointed that these have barely lasted 2 months. I give 2 stars instead of 1 because they were comfortable.

low durability

Hey Edward,

Thanks for the review, this is very helpful! I will give you a call to see if there's a pair that may work out better for you.


Really liked them while they lasted

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I went through a couple different pairs of bibs and competitive cyclist was great at being patient with that process.

Back to the bibs, I really enjoyed the fit of these. They offered a decent amount of compression but were also comfortable. I've had other sugoi products and they always seem to offer the best bang for your buck. The pad is decent, thinner than the centuries but pretty much the same thickeness of the other more expensive options I've tried.

The downside to these shorts comes down to the stitching. Right under the chamoi two small holes have been made after moderate use over the last couple months. They have also began to show other signs of fabric wear where the short rubs against the saddle. I would've expected these shorts to last longer to be honest. Not very pleased with the quality.
