polyester fleece any good?

[ThreePinkFaireez]

Hi guys, would polyester fleece be any good as a cover or even a pocket?

Would it be water resistant or is there some way to make it water resistant??

Thanks!

If you use two layers in the wet zone it should be OK. But it will pill a lot, especially nappies because they get washed a lot.
