OK, so I guess I'm different than a lot of the posters above. First of all, I LOVE the back pockets that come with cycling jerseys. Yes, you can stick a cell phone in a saddle bag, but what about reaching for a snack while on a ride? Stick some easy to eat nutrition in a back pocket and it is easily accessible whenever you need/want it. I am also pretty picky about my cycling jerseys and so will spend a little extra to get one that fits really well. I don't like the ones with elastic on the bottom as they always tend to ride up on me (someone please pass that info to the shop I race for, as I despise the jerseys that comes with our team kit!!). Also, I like them to be snug enough that they don't move around, like slip from side to side, when there is stuff in the pockets.
