I have been using the cloth training pants by Gerber and Carters. They might not be exactly what you looking for they are more like thick underwear and not pull ups. Hope it helps!
We used the Gerber padded undies for a few months before DD started seriously PLing. I'm not sure I'd call them "trainers" but they will hold in a poo and are easy to pull on/off.
