You keep asking this and you are given answers but you just don't like them. Jerseys are meant to be worn outside the straps on they would not have pockets. The straps are often made out out of lightweight material so that they breath better against the skin, and are often "unfinished" I.e. Plain white regardless of the color of the bibs. That last part is not universally true, but frequently is, and is an indication of the design intent to be worn under other clothes, out of view. If you desire to wear you clothes in a different manner than they were designed, that's your right to do so, but don't think you are being clever by challenging the intent of the design. You've found what works for you, great, but what's the point in continuing to ask why everybody else does it differently? Obviously most people prefer to keep thei pockets functional and don't have the big issue with undressing to go to the bathroom that you do, OR if they do they just wear shorts. This is the reason most women prefer shorts to bibs, btw.
