Sizing it forward
I always buy XL bibs (except for XXL Castelli) so I got these in XL and they fit as advertised. These are now my favorite bibs. I'm a middle aged guy with a medium build (read: not athletic) with a size 44 chest and 34 waist who weights 180 pounds in winter. The they fits snug, but not tight (I mentioned I'm not an athletic build, right) with little of the unwanted "play" that can ruin a good day in the saddle. As I write this I'm just disappointed the XLs aren't in stock.
