Hemp Inserts are especially designed for parents seeking natural fibers for their babies whom are in need of heavier absorption. Hemp is well-known to have those properties. These inserts have 3 layers inside composed of 55% hemp, 45% cotton. This is a great combo because cotton absorbs quickly and hemp can hold larger quantities of liquid. These are great to boost our pocket nappies, fitted nappies and AI2 hybrid nappies.
