Brain trainers are specifically designed for overnight bed wetting. They are a pull on style diaper. The absorbency in them is relatively substantial, as a diaper would be.
Big kid training pants are not designed for overnight use. Their tabs are stretchy so child can easily pull them up and down himself. They were developed to meet the needs of the delayed potty training space.
