By the time Luvs came out, I was in my early 20s and I never used them because they were "fitted" with the elastic around the leg openings--because of this they couldn't be repurposed into diapers big enough to fit me. Instead--during that era--my "disposable" era because I still lived with my parents and it was almost impossible to have, wear, wash and hide cloth diapers**--I'd get the large toddler-sized Pampers in the purple box, tape two of them together lengthwise (overlapping them a bit to make them the right length) and use those. But I definitely remember Luvs and when they came out.
**It was almost impossible to enjoy any sorts of cloth diapers, period. There were none made that were adult size that I could find, there was no internet and the only place that sold adult incontinent supplies was a medical supply store. I once went in there and all they had was a big case of flat, non-perfumed, square, thin diapers called "Disposable Adult Diapers". These were probably what was then used at nursing homes. I bought a box then the guy working there kept asking me my name and for my insurance information. He was a nice guy and wanted to be helpful but I didn't want to give out my name, and I was still on my parents' insurance and did not want them to get back a statement listing that insurance had just bought me a box of diapers! He kept asking, I finally told him they were for my brother and can I just pay for these and leave? They were such horrible diapers that after trying one or two, I ended up using the rest of them for "changing pads" or to put under me in case my other makeshift diapers leaked.
And those other makeshift diapers were always either the Pampers taped together as above, or the old "towels and trash bags" thing. It was also possible to buy actual cloth baby diapers in the toddler size and stuff those inside the towels but there again, living with parents it was almost impossible to wash them (I often ended up going to a laundromat). It wasn't until a few years later when I met the wonderful girl who is now my wife, who knew how to sew and started taking cloth baby diapers and sewing them together to make real, soft, flannel, thick baby diapers FOR ME. She also bought baby plastic in white / blue / pink and elastic and made me my first real baby plastic pants. (And people wonder why I married her...ha ha).
This went on well into the 1990s when this stuff finally started showing up on the Internet, which makes it so much easier these days...!
