bobonkerwrote a review of Castelli Podium Collection - Mortirolo Bib Short - Men's on January 6, 2011
I'm 5'9 155lbs and I wear mediums in PI and took a chance with mediums in the Castellis. The are a little tight in the legs, but the length is about right. I think a large would have been too big. Compared to PIs, there is less padding in the front of the chamois and more in the rear. So far, I really like them.
