This thicker insert is great for wearing at night or during longer periods at daytime. The insert is adapted to Poops! PUL and wool cover nappies and is available in three sizes. Due to the insert's specific (butterfly) design, the insert is held in place in the cover and the  surface areas are larger at the front and back to absorb more liquid.
 
The insert consists of 5 layers 390 gsm bamboo viscose/ organic cotton + 1 layer smooth 280 gsm (bamboo viscose/ organic cotton). 
 
Length approx. 30 cm (Small), 35 cm (Medium) and 40 cm (Large).
