These have a super soft velvet outer layer with a hemp inner layer. They have a 4 layer hemp insert attached at the front of the nappy and a snap in insert at the back of the nappy with 3 layers bamboo and 1 top layer of bamboo cotton velour. Super soft against your babies bum. They need a waterproof cover over them as they are not waterproof. For the first wash they need to be washed separately incase the colour runs and they will shrink slightly.
