Conceptually identical to Castelli's bodypaint bibs but with slightly less stretchy and therefore slightly more compressive legs. Sizing seems identical to Castelli., although legs are a bit longer. Like the bodypaint, the single seam on the legs is far nicer than multiple seams. Very comfortable, fairly low volume chamois. Shoulder straps not as soft as they should be, hopefully will soften when washed a few times. Very well made. Feel great, look great. The material of the legs is different from the material of the rest of the shorts, and the pictures make it look like a very noticeable pouch in front. This effect is much less visible in person.
Bottom line is that these are in the upper echelon of the best bib shorts and personal preferences and fit will dictate whether they are among the very best for you.
The real issue is whether these are worth a large premium over other high-end bibs, and that depends on how value-conscious you are since a number of brands I think are 80-90% as good but at 50-60% of the cost.
