Protect your mattress and keep things hygienic with a certified organic waterproof pad. Made with two layers of soft organic cotton jersey on top and bottom and an ultra-thin waterproof barrier in the center, the pad easily stretches to conform to your body and maintain the comfort of your mattress. Features DrySleep™ technology, which effectively blocks liquids from passing through while allowing some water vapor to escape. This helps reduce sweating and clamminess and provides a more comfortable sleep while offering complete waterproof protection. Also blocks dust-mites from penetrating through to the mattress surface. Eliminates common questionable waterproofing materials like vinyl/PVC, phthalates, perfluorinated compounds (PFCs) and butane rubber. Versatile design handles mattress depths from 9" to 16" with an organic cotton skirt and full elastic perimeter.
