These seem to fit well and are a big hit with my son. However, during our struggles with bedtime--he has ripped the 'reattachable' sides--that don't reattach so much, or I have never been able to fix and use them. We have had lots of leaks--as he is older. I would think with the large size should be more absorbency. I'm not a fan of 'training' pants, as they seem to keep it to easy for my kids to fail. While the product is ok, I hope the designers might come up with ways to help with training, rather than a fancy pull up--diaper, cause it is a diaper.
