Armor is for pansies and it's a gorram waste of money. I usually wear cargo shorts, a t-shirt, and sunglasses. The BB's don't hurt for long, if at all. The most pain I've felt from a BB was when it hit me in the lip.
It's a waste? All the gear I have up there can total a gun. So it's either a gun, or TONS of armor. I dunno, it sells itself (Vince reference). Also, I'm not talking about 200Fps guns here, kiddies, I actually GO airsofting and no body just wears casual clothes when a sniper is shooting 700FPS, Also, It's like fitting in, looking as good as the other players, so they don't think you suck or at a different skill level. When you got hit, did you bleed? Did your whole lip cut open? Was it even a Gas/AEG? Or was it a spring pistol because I doubt you've even felt as much pain as when I got sniped on my lip.
