Definitely gadget (miniaturized armor, probably Cal I or II) so that should make it a Cal II or III?

I wouldn't call that a gadget, Alex.  I believe that falls within the design intent of low-profile armor (trendy).

*very* low profile armor? 

[Tegyrius]

When all is said and done, it's just concealment cut IIIA soft armor, using standard materials, in a carrier that looks like a polo shirt instead of a jacket, vest, hoodie, sweater, or suit coat.  It doesn't shed any weight, thickness, or, I suspect, summer discomfort.  Low-profile armor (trendy) has a detection DC of 20, which I think is appropriate for something like this.  I'd reserve gadget armor for protection that exceeds the capabilities of current materials science: equivalent protection in something that actually feels, breathes, and moves like normal clothing, with a much higher detection DC.  YMMV, but "gadget" says "super-science" to me, and I can order this online for the price of a new high-end laptop or rifle...
