This is not about brands per se but quality of chamois for 40-60 mi. rides. I have a pair of PI shorts that are about 6 yrs. old and I think finally worn out. I want to replace them with shorts/bibs with a chamois that will be comfortable for longer rides. I don't want the bulky type that make you feel like you're wearing a diaper but something that fits relatively snugly and is up to the job. As I shop I see a lot of advertising type language to describe shorts. Descriptions like "race" or "attack" don't help me. FWIW, I'm 5'9" and 187 lbs and will probably be down to around 180 lbs in a month or so. Any suggestions?
