Two Layers of Organic Cotton Flannel - Top and Bottom
Highly Absorptive and Extra Soft
Reduces Uneven Temperatures, Sweating, and Clamminess
Ultra-Thin Waterproof Membrane In Center - Waterproof Version Only
Features DrySleep™ technology, which effectively blocks liquids from passing through while still allowing the fabric to “breathe.” Some water vapor is allowed to escape resulting in less “sweaty backs” and a drier, more comfortable sleep. Provides a soft, non-sweaty and comfortable waterproof barrier (as compared to vinyl and rubber). Also blocks dust-mites and other allergens.
