4 layer Bamboo cotton

The 4-layer bamboo cotton holds a lot of wetness and absorbs faster.
It is a great single insert for a light wetter or a second insert for a medium to heavy wetter

They have 4 layers of bamboo cotton. And the edges are reinforced for a more sturdy insert

NB this insert can't be used on its own, it needs to be placed inside a pocket diaper or used as a booster
