Wraps are easier to change with flats or prefolds if the poop gets out than pull ons (though they are not bad). You do need to make sure they are big enough to fit over the prefold.
I like BabyBeeHinds wool wraps. They are machine washable on cold, but run small.
I also like the Happy Heiny snap wool wraps, which are generously sized.
There are several other brands
