I respectfully disagree about the hip armor.
The BMW NP hip armor is practically the same size as the SAS-Tec, and it will fit in the armor pocket of my Rev'it! Classic leather pants. I lose some coverage area at the top because the NP armor piece isn't as tall.
But, even in the skin-tight Classic leather pants there is enough room in that armor pocket for both the temperfoam and the NP if I wanted.
