Made of three layers of microfibre terry, these 3 layer microterry pads are designed to suit your Fuzzi Bunz, Stuffable or Happy Heinys, or any pocket nappy. Microfibre absorbes between the fibres rather than in the fibres themselves as in cotton. It is correspondingly much lighter being a man-made fibre, and looks slim in use. Dries very quicky. Two sizes: Small to fit Small Fuzzi/Stuffables/Happy Heinys and Large to fit larger sizes Medium, Petite Toddler, Large, XLarge.
