The EcoPosh Recycled Organic One Size Fitted Pocket Diaper, by Kanga Care, is made out of rayon from bamboo, organic cotton and recycled water bottles. This one size fitted diaper adjusts to 4 different sizes to accommodate little ones from 6-35 pounds. Because this is a fitted diaper, you will need to use a diaper cover. Each EcoPosh Recycled Organic One Size Fitted Diaper comes with a 6r Soaker made out of rayon from bamboo and organic cotton which makes the entire diaper a thirsty 10 layers. Kanga Care brand cloth diapers are the only cloth diapers uniquely designed with the patented leak protection technology of dual inner gussets. WASH AND CARE: New diapers made from organic materials need to be "prepped". To "prep" diapers, wash on hot (no detergent) then tumble dry on high 3-5 times. Diapers will be at their maximum absorbency after 8-10 washes. For regular wash care: 1. Cold Rinse, no detergent. 2. Hot Wash/Cold Rinse with the suggested amount of detergent (see www.kanga-care.com for full list of recommended detergents). Tumble dry low. All Kanga Care products are designed and invented by Julie Ekstrom, mom and CEO of Kanga Care, and distributed world wide out of Golden, CO.
