Vaughn VP 7800 Velocity 5 Chest & Arm Protector
The 7800 is made to protect you, while working with the other pads to feel comfortable without leaving any parts of your body uncovered. The arms are made to give room for the blocker and catcher, and abdominal region is incredibly flexible, so it won't rub uncomfortably against your pants. It also features lower chest extensions that can be adjusted to fit against you just as snug or loose as you like. The icing on the cake is that it's made from the same protective equipment that the military uses, so you know it'll last the entire season, and then some.
