The insert is 1 layer stay dry bamboo charcoal fleece, and 3 layer charcoal infused microfibre core.
** this insert is not bamboo but rather microfibre infused with bamboo charcoal. Due to the charcoal fleece, this insert is ok to touch baby's skin. Can absorb very quickly but is prone to compression leaks like any microfibre. Great for flood wetters - babies who can pee a lot at once and 'flood' nappies. For older babies or heavy wetters place a natural fibre insert underneath for a well layered nappy.
The inside microfibre is also infused with charcoal, unlike many cheaper versions.
Size 13x33cm weight and absorbency (dunking test): 56g/ 336ml
