Do all jerseys have this? I would like one of these so that I can stop wearing a little sling bag to carry my stuff.
New rider? Likely.
Those are cycling jerseys. The pockets are there to hold tubes, C02, food, money and anything else that you need. This takes the place of a saddle bag (which you don't need).
Buy one or 2. Only ride with them.
