Natural, untreated tussah silk with large nubs and slubs: Starlight Upon The Sidra has a natural, raw appearance with various shades of grey on black, to create a sophisticated, classy and modern look. Tussah silk may contain small pieces of straw, which will come out with washing and use. Woven in our signature blackberry weave, the wrap is supportive and will break in easily. This is an all-year-round wrap. With its loose, airy weave, it is suitable for warm weather. This wrap can be machine washed at 30°C on a gentle wool/silk program at 400 RPM.
