honestly mate, the only padding you need is a mask!
paintballs do not hurt that much, unless they get you right on the spine..
just wear like jumpsuit kinda thing so you dont get paint all the fuck over your clothes and haev alot of extra money to buy more paintballs..
the hopper holds like 200 balls each and i went through like three hoppers..
just keep low and keep moving, once you've been hit once you know what its like you dont give a shit..
take it easy mate and dont be a fucken pussy.
