I went thru dozens of bibs and short (Pearl Izumi, Giordona, Castelli etc) while they worked for a while eventually they all didnt yield the result I wanted for the long distance aggressive riding I do. I went with the Pactimo 12 Hour Bib havent looked back. What i've gathered over the years is the chamois is the key if that is made by a quality supplier you will probably have better results, cheap gel or foam chamois just dont cut it for long days in the saddle or arent comfy enough to settle in on shorter rides.
