The Clean Bedroom is proud to offer these superior quality organic pillow encasements with fabric so tightly woven they discourage dust mites and bed bugs from taking up residence in your pillow. We are pleased to offer alpaca duvets, mattress pads and pillows with outer coverings of 100% GOTS certified organic cotton 230 Thread Count (TC). The covers are made from 100% organic cotton for total breathability. The covers are easy care: wash in warm water and dry in a warm dryer or hang to dry. Please pre-wash for a better fit. A nylon zipper is featured for ease of use and comfort.
