The system is made up of two parts: washable cloth 'pants' and disposable liners. Yes, yes, they have a disposable component - but it's not as bad as you think. The liner is made of only pulp and paper products, no plastics. That means the liner can be flushed in a toilet or, if you have to throw it in the garbage, it will break down in 50-100 days as opposed to however long it takes a traditional disposable diaper to decompose. But wait, it gets better. If the liner is only wet, but not dirty, the liner can be tossed in a compost bin to help provide rich nutrients for our lawn and garden.
The cloth pants require an upfront cost but the liners cost less per unit than a traditional disposable diaper.
To me, it was the perfect compromise. I get the reduced environmental impact and (some) cost savings associated with cloth diapering without the increased workload.
Of course, I haven't put them to the test yet. Once I have I'll report back and let you know if they're as great as I think they're going to be.
