A smooth to the touch 280 thread count organic cotton sateen crib duvet cover perfect for all weather, especially the hotter season. The organic cotton has a cooler feel than polyester due to its natural breathability. Hydrogen peroxide whitened for a simple elegant feel. Softens further after washing. Machine wash and dry on regular. Add 1/4 cup of vinegar to the load to increase softeness. Fabric is not pre-shrunk and will shrink to the proper size once washed and dried. Made here at our San Diego, CA Facility. Ships out within 1 to 2 business days.
