As my cloth diapering venture into Wool Covers deepens, I have to say that I’m in love with this method of cloth diapering. Basically, this is how humanity has diapered its babies for centuries. An absorbent cloth diaper, covered in lanolin-rich wool pants. And it works! The concept is simple, Sheep naturally secrete lanolin onto their wool, which protects them from rain and snow. Essentially, by lanolizing the inside of the wool diaper covers, you are trapping the moisture inside.
