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.

My Go-To BIbs for Big Rides and Every Da

Familiarity:
I've put it through the wringer

I've owned at least 6 pairs of Castelli Endurance Bibs (v2 and v 3) over the years, and love them. The quality is excellent, the material lasts well, and to me the Progetto chamois pad is the best I've found, especially for those long days out (4-10 hours). The chamois is relatively thin, so you don't get that bulky diaper feeling, but it has the right blend of densities to be comfortable for the long haul. As noted in nearly every review, Castelli bibs run very small, and these are meant to have a snug, compression fit, so go up at least one size, and maybe two, compared to other brands. At 6'1" and 193lbs, I wear size Lg or XL in most bibs, but in Castelli I get XXL, and these still have that compression fit. Some reviewers here commented on these being sheer in places, but I suspect they may have been referring to a different model (maybe they got the indoor or liner versions?). There's nothing sheer about these, and they offer good coverage everywhere it's needed. On that note, I also appreciate that the shape of the straps bring the mesh waist area up and over any slight love handles some of us may have, so there no waistband cutting in or creating that "muffin top" look. Some have also noted whet they thought was an unfortunately placed seam, but it's not like a seam runs right up the middle of the crotch (like some Pearl Izumi bibs); look at the pics here and you'll see it arches above the nether region. With proper "placement," I've never had a problem with any seams rubbing anywhere with these bibs. If you like having side cargo pockets, Castelli now has the Unlimited Endurance Bibshort, which uses the top of the line Progetto chamois, with a softer material throughout the body than they use in the Endurance 3 (less compressive), and the same overall cut. I like having side pockets, so those are my new overall favorites, but for rides when I'm not carrying as much stuff, I'll definitely keep some of the Endurance 3 bibs in my rotation. I also bought my wife the women's version, and she loves those too. Highly recommended!

Runs way too small!

Familiarity:
I returned this product before using it

I bought a large thinking this would be enough of a size up and I was wrong. The large size was way too tight at the crotch area which is not a flattering look and it felt uncomfortable. Unsure if I will re-order the XL or just go with another brand.

Unfortunately a little disappointed

Familiarity:
I've used it once or twice and have initial impressions

First thought is I should have ordered two sizes up rather than one compared to my other bibbs to obtain maximum comfort. Second concern is a seam around the men’s kickstand area. This is just enough to make it a noticeable distraction. Rode a short 35 mile ride and that’s my opinion of the product.

Run smaller

Bought these as a gift and will have to return. They run a size smaller and surprisingly the front and sides is see-through.

Size Bought:
XL

I bought these Castelli Endurance 3 bib shorts after seeing positive reviews from multiple sources, which also noted that they run small. I generally get a Large in riding shorts, occasionally even a Medium, so after double checking the sizing chart I went with XL. The thigh binding was snug almost to the point of cutting circulation and the straps felt tight on my shoulders. I coincidentally discovered an older pair of Castelli bibs that I bought some time ago. They are also XL and they fit ok, except the straps are thinner than I'd like. So it seems they've shrunk their sizings over time! I'd recommend getting two sizes larger than normal if you'd like to try these. Personally, I think I'll go back to Rhapha- better fit and cheaper price. Note: Backcountry has a generous 90-day return policy, though I have to pay for shipping.

Great shorts with one MAJOR design flaw

Familiarity:
I've used it once or twice and have initial impressions

These short have the potential to be my go to everyday shorts if it weren't for one major design flaw. As others have mentioned, the modesty panel in the front is much shorter than other shorts out there. The problem isn't a modesty thing though, it's a comfort issue. Because it's so short it puts the stitching in the one place you don't want it, right on your "soldier". Luckily I only went on a short 30 mile ride and even with that it about rubbed me raw. Glad I didn't do my long ride today!

XL

I bought these for my boyfriend to replace similar ones by the same Italian company. He reports they are fantastic. They run SMALL so definitely order at least one Dixie larger than usual.

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.

Premium pad without breaking the bank, runs a little small but great if you like compression bibs

Amazing pair of bib shorts

Familiarity:
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.
