I had no idea jerseys and jackets had pockets too. Thanks for your valuable contribution.
You must be joking.
Why would you want pockets on your bib shorts? Because your trousers have pockets? Are you trousers as close fitting as bib shorts? I can't imagine what pockets on bib shorts would even be like.
But here's something you may be interested in: They make loose shorts that have slash pockets with zippers, which is ideal - keeps things from sliding out while riding, but comfortable to use. I wear these if I'm going to be spending much time in public off the bike around a ride (I don't bother with a belt, though).
These are from Rab. I don't know if they're a current style, but there are probably others.
