Shaped onesize nappy (birth to 15kg). Needs a cover. This one size nappy is, as it says, incredibly soft and also absorbent. There are poppers to adjust the size for smaller babies and hook and loop fastenings. It comes with its own booster and is easy to use.Quite bulky but extremely effective and available in organic cotton. If you want something natural and economical then this is a good choice. Fairly easy to use, but on smaller babies the adjustment poppers can come undone when you're fastening the rest of the nappy and this is somewhat irritating. If you have this nappy, you don't need any others (for night-time, older baby, etc.); so it's a great money-saver, even in organic.
