I'm considering giving the adult diapers you can only buy online a try, but I'm a bit concerned about whether or not they will fit. My choice is going to be either Bambinos or ABU Cushies with the most babyish design they offer. I am well aware from having read other threads on here that ABU has customer service issues and that they don't absorb as much as Bambinos, but they do look quite a bit more like baby diapers. I could maybe buy a sample size pack of each and compare and that way I'm not risking too much money with Cushies if for some reason they don't arrive.
As mentioned earlier, I'm not sure how well the smallest size they have for either of these diapers will fit me. I've found the L/XL Goodnites to be a pretty much perfect fit for me and I do enjoy wearing them. I'm somewhere between a 30-32 inch waist and weigh around 150 pounds. Of course, the other advantage I see to Goodnites is the fact that I can buy them in a store and they are quite a bit cheaper than Bambinos.
