The differences between the Bamboo and Organic are colour and fabric. The Bamboo made from viscose is our softest most popular Belly Bandit® to date. The Bamboo Belly Bandit® is made for the "green" mom who spares no expense! Ecological; smart; unbeaten, and all together our comfy cosiest! Available in Black and Natural. The Organic band is made from organic cotton and is only available in pink to support the Shades of Pink Foundation. A portion of all proceeds go to support this wonderful charity, read more about it here.
