We never use chemically processed pulp (such as rayon aka viscose) or synthetic materials in our pads. Instead, we use fluffed wood pulp in the absorbent core of our pads. Our pulp is sustainably sourced from fast growing, Scandinavian pine trees – which is very absorbent! We mechanically process the wood to make it soft and fluffy – this fibre structure is more absorbent than using cotton alone. Pulp is natural, renewable, and more sustainable alternative than the use of super absorbent polymers (SAPs) found in most conventional pads. The cover is made from certified organic cotton, and this sits next to the skin, acting as a soft cover to wick away leaks.
