I absolutely love these bibs! I have a pretty strong chamois preference; a pad with any grooves or pressure relief channels causes rubbing/saddle sores with my anatomy. Before these I'd only liked Castelli bibs. The chamois on these are comfortable, if a little thinner, making them good for road/gravel rides under 30 miles. I also reached for them on MTB rides with a t-shirt, as I could stash my phone and snack in my pockets. I'm 5'7" 160 lbs, medium was snug inititally but broke in nicely.
