Most of the camo clothing available do almost nothing to actually conceal you and break up your outline in the woods. They are all some sort of sticks and leaves pattern that's made up of browns and blacks that blend together and turn into a big human shaped brown or black blob at 20 yards or more.

Almost none of them have anything that actually breaks up an outline of a human in the woods.

ASAT and Predator are two of the best camo patterns available but they are so much lesser known because they aren't marketed like the Mossy Oaks and Real Trees are.

There is a test of camo patterns somewhere on the web and the most effective pattern in the test was a Hawian shirt. After it was converted to gray scale the persons torso all but disappeared into the tree he was standing in.
