I have been wondering the same thing. The tan back ground on my 3d suit has lightened up alot and thought i read on a website somewhere that there was a problem with the dye or something. I purchased just the shirt from asat and wear some mobu pants, the tan on the shirt i got from them is darker, like the tan in the garments i got from dayone. I do belive the asat breaks the human form up good though.
