I like Giordana, but there seems to be a fair bit of "ymmv" given that different chamois fit differently. (I also have a pair of PI and Louis G, neither fit as well). What does he have now? Do they fit him well? Of he has a lower model from X company, you could get him a nicer pair from same company. I went from Giordana Fusion shorts to Lazer bibs (ignore the bib part, just talking chamois here), the nicer chamois is really noticeable, but the fit is consistent
