Why We Like The Castelli Endurance 3 Bib Short

For our longest rides where a comfortable kit keeps us going, we put on the Castelli Endurance 3 Bib Short to ensure we finish our ride as strong as we started. The bike-specific anatomic cut offers a perfect fit in riding position, while the Endurance Evolution fabric provides excellent muscle support and quick-drying properties. For greater long-distance comfort, the Progetto X2 Air Seamless seat pad keeps our perineal area padded for long days in the saddle.

Comfortable but runs small

I've used it once or twice and have initial impressions
Size Bought:
Medium and Large
5' 11"

I ordered medium and large after reading other reviews and sure enough I could barely get the mediums on and they are on their way back to Backcountry. The large fits well. I have done a couple of rides and they feel great.

Amazing pair of bib shorts

I've put it through the wringer

I really do love these. Sizing up for sure, but even then it will be tight especially on the shoulder straps. These are comfortable and should be worn in the biking position, this it's right when standing up.

Will become a long distance favorite

I've used it once or twice and have initial impressions
Size Bought:
5' 7"

After a couple break in trainer ride I can tell these bibs will be a go to over the summer season. Typical excellent Castelli quality, really the best of their chamois, and very comfortable straps and grippers. Oddly, I did have the need to stretch them out over the course of a few ride to get them comfortable over the shoulders as I have had to do with other Castelli bibs. I'm 5'7, 160# and the mediums fit great

Runs very small, poor quality

I've used it several times
Size Bought:
5' 10"

I've been a Castelli fan for many years and own several shorts and bib shorts. Lately their sizing has gotten smaller than it used to be. I normally wear a Med in an American brand so have ordered Large for Castelli and it fits fine. Lately the Large is very tight. Much tighter than it used to be. I've also had issues with the threaded seams coming undone on the last 3 shorts/ bib shorts I have purchased. This happens after only a dozen or so rides. I'm done buying the Castelli brand.

Runs very small

Size Bought:

I know that bibs are supposed to fit tight but these were so tight/stretched when I put them on that they were nearly see through in some areas. They run small, even for Castelli.
