Silk and wool gentle touch. Youll hardly know you are wearing it! Silk on the inside and wool on the outside. Silk fabric is soft and smooth against your skin. Wool fabric is rough and breathable, smooth and light to the touch. By laying two layers of fabric together in a single fabric, it traps air and maintains a comfortable moisture and body temperature throughout the year. Since the fabric is woven into a tube, there are no seams on the sides, and the hem has been treated with a merrow, reducing the tightness. Silk and wool are natural fibers. Please handle with care. We recommend hand washing with mild detergent without fluorescent agents. Avoid using bleach, tumble dry or fabric softener. When using a washing machine, please be sure to put it in a laundry net and wash it on a gentle cycle. There may be some shrinkage or pilling in the wash. Please adjust the shape and dry it in the shade. ·As these are natural materials, sizes may vary slightly depending on the season and lot.
