The Elemental Joy has been designed for those on a budget. They are great value but, unlike many 'cheap' nappy brands (bought through the likes of Ebay), they are made by the much-loved, long established US company 'Cotton Babies' who make BumGenius and FLIP nappies. This company ensure safe, quality fabrics, so no substandard elastic or unsafe poppers.
The pocket wraps come WITHOUT inserts but can be stuffed with several different inserts which you may already have from previous nappies (or bought cheaply second hand). The sizing of the Elemental joy is similar to the BumGenius Original V5 (although it is a little bigger than the V5) so the V5 inserts can be used in both. If you don't already have inserts the Elemental Joy Birdseye inserts have been especially made to go with them and provide an adjustable fit. Older babies may however require something a little more absorbent.
The wraps fit from around 8-35lbs so are, pretty much, 'birth to potty' nappies. Saying this, I suspect that 12lbs is a minimum weight from which the nappies will fit well (depending on the size and shape of baby).
PUL waterproof outer. Soft microfleece inner.
Gentle elastic to help prevent leaks.
