Plus, though it would look cool, as Adam pointed out you will be a slow target. You'd get hit, most likely multiple times, close to the start of the round. Safety issues aside, it's not a logical plan as far as Paintball gear goes. I would shift plans, and make Marine or ODST armor for Paintball. Motorcycle helmets look somewhat similar to ODST, and their body armor allows for rapid movement. Your clothing would be most likely BDU's or Urban Camo dress. The material used to make BDU's is great for dampening a paintball's sting. I would highly recommend shifting costume layouts if you intend to stick with the Paintball theme.
