Fitted Nappies are the super absorbent part of a 2-part nappy system. They work in the same way as a traditional terry nappy, but they require no folding, as they are already shaped to fit around a little bottom! They require a waterproof nappy cover. Fitted Nappies can be found in a range of fibres incuding cotton, bamboo, and microfibre, and with a range of fastenings (i.e. Aplix, Poppers or Nippa). Fitted Bamboo nappies can be especially fantastic for night-time use because of their super absorbency.
