Pillow with quilted hemp case on a zipper.    

Hemp is a natural anti-allergenic fibre organically grown without pesticides or herbicides. Hemp textiles support the body`s natural thermo balance by letting it breathe so moisture does not build up during your sleep; the moisture evaporates naturally, lets the air through so you will never feel too hot --machine washable
