I guess if the foam piece AND the SAS Tec piece both fit in your slot in your jacket it's probably not a horrible idea to use both. I would think this would get really uncomfortable and would restrict air flow. The sas tec armor manufactured and tested to withstand the hardest impacts by itself, so it's not necessary to use both. Also, the sas tec piece is much more flexible and body conforming then the foam, so the foam might restrict you from getting the full perks of having this armor.
