Okay, I'll make the first Fred reply!
I'm a bit chubby and find it hard to get a comfortable fit with a jersey. I prefer a synthetic T shirt with the same breathability of a jersey at a fraction of the price with lots of solid bright colors to choose from. UnderArmour is my favorite brand. We have an outlet store nearby.
Rear pockets? At 73 I've lost the flexibility to reach back there. I use a small top tube bag for wallet & phone/camera. Pockets of baggy shorts for off-bike use.
I can't tolerate thick, maxi-pad diaper wads on the butt. Only thin ones if I wear cycling specific shorts..
