Your SmartipantsTM starter package comes with 1 SmartipantsTM reusable diaper, and 1 Smart SleeveTM Insert. SmartipantsTM diapers are both easy to use and easy to care for. Just place the absorbent insert into either side of the sleeve, and it will stay snugly in place until you remove the diaper from your baby. Once the diaper is removed, there's no need to take out the insert -- it comes out in the wash! All of our diapers are proudly made in the USA! Smart for your baby: SmartipantsTM diapers feature our Leak-Guard Technology, keeping moisture contained, and your baby dry. Our diapers are made with "breathable" fibers and are free from any chemicals or irritants. SmartipantsTM reusable diapers are designed to grow with your baby from newborn to toddler, babies 7lbs - 35lbs. Smart for your wallet: Instead of requiring 7,000 disposable diapers, the average baby needs only 24 reusable diapers, resulting in a net savings of nearly $3,000.00! In addition, SmartipantsTM are not only the most advanced reusable diapers on the market, they are also the most affordable! Our products are all produced in our own local manufacturing facilities, and we are able to pass on those savings to you! Smart for your environment: Every year our country contributes roughly 3.4 million tons of disposable diaper waste into landfills. Using reusable diapers not only reduces the amount of solid waste, it also reduces the amount of harmful chemicals, oils, and trees required to produce them!
