Papa, by "organic" do you mean "eco-friendly?" If so, I understand that only diapers for infants currently claim to be "organic" or "eco-friendly."
Also, no mainstream adult diapers are truly biodegradable.
Even the few that use this label will not degrade in a landfill due to the lack of oxygen. However, you can tear apart the used diaper and use the SAP crystals in your garden.The best diaper with a cloth-like shell that I have tested is the Seni Quatro.
It is a premium diaper. They advertise 86 ounces of useable capacity. I doubt this, but they do have a very high capacity - probably akin to Dry 24/78. Also, they stretch less than any cloth-like diaper I have tested. You can buy them from XP Medical. --John
