Protect your baby's new mattress and keep their crib hygienic with a GOTS certified organic waterproof mattress protector. Made with two layers of soft, organic cotton jersey on top and bottom with an ultra-thin waterproof barrier in the center, the pad easily stretches to conform and maintain the comfort of the mattress. It features our DrySleep™ technology, which effectively blocks liquids from passing through while allowing some water vapor to escape. This helps to reduce sweating and clamminess, providing comfier sleep and complete waterproof protection. Our crib mattress protector also helps to block dust mites and pet dander from penetrating through to the mattress surface, and it's made without vinyl/PVC, phthalates, butane rubber or other questionable waterproofing materials. Say goodbye to bedtime allergens and hello to cleaner, comfier sleep for Baby! Machine wash and dry.
