@jayrashman If you want no plastic then pockets are not going to work for you. They do make cotton pockets (I know Thirsties does and I think there is one more I can't remember) but they all have polyester outers that will touch baby at some part. But if you're okay with just the outer being.
If you want to go for plastic free diapering, wool covers can be lanolized to contain and repel liquids. My favorite is Babee Greens with a fitted underneath, it's just so easy to use, but just now I put my toddler down for a nap in a Green Mountain prefold with wool Babee Greens shorties. There are a lot of options for wool systems, Puppi diapers have an all-in-two type system with their covers that sort of works like a pocket-- they have a snap-in insert that you can stuff with your absorbency of choice, and it's all natural fibers. And alpaca covers can be used similarly but doesn't need to be lanolized at all-- check out Lunapaca. They even have metal snaps.
All those covers need to be handwashed though. I know there are wool companies that make machine washable covers, like Bumby or Wild Coconut Wear, but they contain an amount of spandex, so that's a little bit of plastic.
