The Silk interior makes it soft and breathable. Silk is known to be hypoallergenic, anti-bacterial, non-irritant, anti-viral and beneficial for the skin as it helps it stay healthy and smooth (doesn't draw moisture out unlike cotton). Oh, and did we mention no more Maskne ? Silk is simply the best fabric for your skin.
