Hypnorm, they are pure wool and lovely soft ones like merino and alpaca. You use them instead of a wrap so very breathable. You lanolise them and they work in the same way they do on a sheep, they evaporate moisture away from the nappy so also stop the nappy from getting to wet making them ideal to use as pajama bottoms. They are often a little damp feeling by the morning you just hang them to dry and keep resusing them, only when they start to smell when dry do you need to hand wash them which is about every 2-3 weeks.
