These bamboo inserts are made of SIX layers of bamboo terry fabric.
Pure bamboo inserts are amazingly absorbent and can be used by itself or in combination with a microfibre insert. It is recommended for bamboo to be slotted under the microfibre insert.
Tip: Soak the insert for 24 hours in water before first use. It may take up to 10 washes to reach full absorbency.
