Having used cotton bacon, I can say, that it is by far the most superior cotton I have used. With that said, I'm just using some Puff japanese cotton pads, and it's doing me just fine. I can't find any old cotton bacon bags lying around, but I guess it's apparently medical grade cotton. All I know is the stuff wicks max vg quicker than anything else I've seen and had zero taste, but with the price, it can be costly to keep buying the stuff. It's been a while since I last bought a bag.
