Where can I buy some Black Camouflage for paintball or airsofting?

There is this really cool Black Camo that has the woodland style design but instead the main color is black and the other colors are like grey or something. I saw a man at the Cactus State Fly-In with a pair of cargo shorts with the design so I know I can get them somewhere. One of my friends said it was Dark Arctic Camo but I am not sure. I want to know where I can buy some BDU's like that. Can anyone help me?
