I am a shorts kind of guy. My only complaint with bibs is the feeling of the shoulder straps slipping down(whether they actually do or don't). They kinda bother me. I have good muscles from my neck to shoulders that taper downward and that makes for that feeling. Oh well.
The other thing I don't like is the extra layer on my chest and belly. In the summer it is HOT here and that extra layer is a bit much sometimes. Don't like the feeling of something clinging to my belly. I'll take shorts, thank you very much. But if you like bibs, great!
