You can tuck them into a pocket diaper or place them directly against the skin for extra absorption. While the dense five-layer design means they take a little longer to dry in the machine compared to synthetic blends, the superior ventilation and ability to wick wetness away make them a total game-changer for eco-conscious parents.
