I'd rank these with LUVS, they just don't work as good. I loved them when I opened the package, they look like brown paper bags but much softer, even up until I got them off the baby who was soaked into his car seat. I hate to say it, but I won't use these.
We use disposable when we are out an about a bit, since it is easier to travel with then cloth. We gave these a shot and still have a pack of them (since we don't use them very often packs last a long time), but they aren't as great as I was hoping leak protection wise, and when I looked into to them they don't biodegrate any better then the less green brands. Though I do like that they use less chemicals, which is my major complaint with disposable diapers as far as in relation to using them on my baby. So they have their good points and their not so hot points, but then you win some and you lose some.
These diapers perform very well, in fact even better than most other disposable diapers. If you worry like do about putting harmful chemicals against your babies skin (and don't want to do cloth diapers) these are a good choice. There are now a variety of chlorine free diapers out there, but these are good and what my wife prefers to buy.
So I don't have tons of experience with diapers (being sans babies myself)...but I recently got a bit more when travelling with some cousins of mine.
My little cousins are able to crawl, roll, and walk about quite well in these Seventh Generation diapers. I think it's a good sign when you can play with a baby and the diaper doesn't get in the way. Not to mention, they hold up well, are quite absorbant, and best of all, they don't irritate the baby's bum (one of my cousins is highly sensitive) as they are chlorine/dye/etc-free.
So while the drawbacks of disposables are clear (i.e. sending waste to the landfill), if you're on a trip and can't launder cloth diapers...or if you just need a quick fix of something easy...these are a great option.
I try to use cloth diapers whenever possible but when I 'm in a bunch this is the best alternative! Seventh Generation diapers have a unbleached paper look to them. The fit is good so they seem comfortable. There's no leakage if you change before every feeding. The diapers don't contain the toxic gel however they do contain a gel for absorbency. I wished the diapers were biodegradeable or even made from recycled materials. They are still ending up in landfills. That is why they get 3 stars.
