Bamboo is a material being used in cloth diapers these days due to its sustainability and absorbency. Bamboo is a good, green option since the bamboo plant is rapidly growing and regenerates itself quickly. According to allaboutclothdiapers.com "Bamboo is naturally anti-microbial, anti-fungal and anti-bacterial. This porous fiber absorbs moisture and wicks it away from the skin, leaving baby cooler and drier than cotton or synthetic materials."
Birdseye cotton is a classic cloth diaper material which has been used for years. The weave of the cotton collects the moisture. This material is fast drying, making it great for line drying.
