PAWS DOWN, Little Pawz are my favorite and the most thickness I ever had (Hence, one of the reasons why I love them so much) Medical grades at the hospital doesnt even come close to the quality of this, as these arnt only thick, comfortable, and cute, but can absorb just shy of 1 and a half
GALLONS I would highly recommend for thickness that you get these.
I hear ABU simples can absorb the same, but I never tested out that thickness for myself, if you dont like the design.
