Nicely padded. Fit is on small side. Usually medium to large, returned for xl. Still very tight. Wearable but very snug. Maybe after a few washings and wear....

Slightly tighter than preferred, however, they haven't been worn enough to stretch them...I have the previous model of these and they are my go to. Had to get new because stitching for chamois came out...no biggie, they just got worn out. Love Castelli.

This is my second pair Endurance X2's and I will buy them again, I have had a different pair of Castelli come undone on a seam but they were replaced no questions asked Castelli seems to take care of their customers ! This Progetto X2 Air Chamois is awesome !! Most of my rides are 50 miles or less with a few up to 100.
Review by Jon
Great fit and I have used them on a few 50 mile rides so far and they are extremely comfortable. The first pair I received had a seam that was coming undone, but WB swapped them out and the next was perfect.

I've been holding off on purchasing this bib, finally went for it with the massive discount. I have 3 castelli bibs aero race, velocissimo due, and this one, this is the most comfortable bibs I have of Castelli so far. I also like the compression it offers, and modesty coverage at the front. Only little issue is the length, about 12 to an inch shorter than I'm used to for the castelli sizing.

5'11, 190lbs and probably should have bought the XL. The L is a tad small right now so when I lose my last 10lbs of winter weight they should fit perfect. They next Castelli bibs I buy will be XL's. I prefer wider straps which these do not have and are kind of annoying to get them to sit right. Could be because I need to size up?

Greta fit, I mean tight! - for me, size M. Best chamois I think.

I use this new bib for all my weekend rides which are 60 to 70 miles a day.

These bibs are a little lower quality than the top of the line, but the price is lower. They do the job.

Love the fit and quality, but surprisingly, I have found that the Kiss Air chamois works better for me at long distances.
Review by Tim Chamberlin
quality issue with stiching coming loose on front of shoulder strap attachment, return was handled very easily and quickly. Castelli bibs are still the most comfortable cycling shorts made period.. need to address some minor finish issues, perhaps was a quality escape on that lot of shorts.

I have no criticisms. I have always like Castelli. It has a sleek appearance and it even sounds fast when you put it on.

I had a pair of Castelli bib tights with the same chamois as these (Endurance X2 shorts). The tights' chamois was very comfortable and the tights were mostly well-made. So I decided to try the bib shorts.
The chamois in the shorts is also very comfortable. The shorts are very tight, however. I sized up as recommended to an XL (Pearl Izumi larges fit me very comfortably). I am 6'0 170 lbs, with maybe larger thighs than the numbers would indicate. The Castelli XL's are the snuggest shorts I own, and the straps could be longer too. I tend toward preferring snug shorts, and decided (barely) to keep the XL Castelli's, so my choice, but I will try an XXL next time. After a few miles, I get used to the XL's, but they are really snug when they first go on.

As usual, the Castelli brand delivers quality technical garments that in my opinion are as good, or, better than any premium brand out there, and at a more reasonable price point. I've been a fan of Castelli for many years, having tried just about all of its competitors. My only complaint is that sizing, Castelli has always been very consistent in this capacity, but this time, my usual sizes ran smaller than usual (and no, I didn't get bigger).

The Castelli Endurance X2 bib short are a great bib. I ordered the medium, I'm 150 lbs at 6'1. The fit and chamois is perfect. No movement at all. I have nothing to say bad about them. I wore them in the winter with some leg warmer, I believe the temp. was around 49-55 and I had no issues.
Review by richgfcst
Excellent bib-short for rides 63 miles or less. Comfortable with compression but not too much compression when they fit. However last year I was 15 pound overweight going into the season and these were too tight till I lost the first 5 pounds. Then they fit great.

Purchased when on sale and am glad I did. Ride comfort on par with bib shorts that cost well over $200. And I'm not sure where all the must order one size up sentiment is coming from. I'm 5'11 165 lbs size 31 waist and typically wear Medium for all my clothes, and Medium fits perfectly. I would say these run true to size.
