forgive my horrid paint skills, the white is the straps, the red is the kevlar pad.its the side strap and the upper shoulder peice poking up. look at a peice of class 2a armor on the back and you will see it, its not the most flexible thing in the world. You can clearly see the edges of the panel on the vest, as most vests have about the same profile as a "wife beater" shirt without the shoulder straps.
