armor inventory differences

[rockarfett]

I am wondering if anyone knows how the armor types differ in inventory space. I read that it will grow as you upgrade to agile and reinforced, but I wonder how much. I am curious since I am somewhat tempted to pick up both medic and engineering certs but then I would have to carry plenty of stuff in my inv since I would need both med cannisters and ACEs. I was hoping agile armor might be enough but perhaps I need reinforced for the extra carrying capacity.
Does anyone know anything in this area.
