I have no idea how close the ABU Kiddo were in the cut/fit of the actual Kiddo brand. (Kiddo launching in the US might be the principal reason that it was discontinued from ABU - but that's conjecture). They fit me OK - but I wear XL, which the regular Kiddo line does not yet come in. I also only ever used them in the daytime as the very few times I ever tried wearing to bed I was guaranteed leaks.
If they ever do come out with an XL I'll probably still buy some - basically a mixed case so I have a few of several different styles. But they'll never be my primary choice.
