Dan Mcwrote a review of Castelli Endurance X2 Bib Short - Men's on May 30, 2017
Familiarity: I've used it several times
As you may be able to tell from the other reviews, this bib (as with all Casteli gear) runs small. I'm 6' 1" and 190 lbs. and the XXL fits OK (I'm a large in Pearl Izumi bibs). My typical riding weight is 185 lbs. and I think the bib will still fit the same after I drop the weight. Fit is OK in areas and too loose in others. The "Endurance" chamois has proven to be average at best. Not for rides over 2+ hours which is disappointing. The bib straps are very narrow. I have broader shoulders and wider straps would be a lot more comfortable.
