I searched the net and I found that you can get a Spec Ops The Line bandana, only at EB Games.
Although it's an Australian site, EB games is the Australian Gamestop, so may be available in America soon.

Although it is PC, it's available for all versions of the game.
Also you can get a T-Shirt with the games cover on it, but I do not know if it will be available in America.
