These popular, high quality wraps are made of 100% pure newly-woven and felted wool, with gussetted legs and gentle elastication to give a good fit. Wool pants keep your baby dry and are the most breathable of nappy covers, they are particularly recommended with nappy rash and eczema. Using wool lowers the temperature in the wrap by several degrees and so is ideal for night time use. They come in several sizes but you will not need to purchase every size as there is much overlap. These wraps have a hook and loop fastening and have an extra popper in all but the size small so that the wrap cannot be removed by the toddler.They are machine washable at 30 degrees and require regular lanolinisation to retain their waterproof qualities. These wraps are not pre-lanolinised so will require treating before use.
