These Overnight pads are made with a 100% certified organic cotton top sheet with a combed and carded 100% cotton core, which is naturally more absorbent. The pads have a leak proof, yet breathable, eco-material backing. They are extra-long with wings for stay-in-place protection. Individually folded and wrapped in recycled plastic. Certified organic by GOTS, ICEA and VEGAN OK Plastic use is offset through earth and ocean plastic clean-up through a unique partnership with Plastics for Change.
