Coterie The Diaper review

Coterie's The Diaper is the most documented premium diaper we compared, and its specs back up the price. Coterie says the absorbent core holds over 16 oz of liquid, based on lab testing of Size 4, and gives up to 12 hours of protection, so one diaper covers days and nights. It is totally chlorine-free, with no added fragrance, parabens, latex or lotions, and it is EWG Verified, dermatologist tested and third-party lab tested in Germany. Coterie publishes a full ingredient list. Monthly boxes hold 6 packs sized to typical daily changes: 186 newborn diapers, 168 in Size 3 and 96 in Size 7, and an N+1 box splits newborn and Size 1 for babies about to size up. Subscribers save 10% and can delay or cancel by text. The downside is cost: boxes start at $95 a month, the highest price we verified.
