Our Organic Silk uses the highest grade 22-momme organic silk, densely woven to gives a luxurious and long-lasting softness. Naturally hypo-allergenic and temperature-regulating, this breathable fabric is able to maintain the body s own moisture levels, helping to protect the health and suppleness of hair and skin. This unique satin weave uses a process of four over, one under to maximise the number of threads visible on the upper side of the fabric. The result is a medium-weight fabric with rich satin softness. Our range of pillowcases are dyed and designed to complement our range of Supima® sheets, to help you create stylish layers in your bedding. This pillowcase range is available in standard size.
