Microfibre is a super absorbent. 
Being very absorbent, you can double up on these inserts inside your shell for a great base to loading up your nappy. 

Keep in mind to always use microfibre away from the skin, meaning, always insert them inside the pocket so they aren't touching your babes skin. Though microfibre can hold loads of moisture, it fails to draw moisture away form the skin so if it against the skin and when wet, it can cause irritation or even nappy rash.
