Our Sateen is made of the highest quality 100% organic long-staple cotton. The weave creates a subtle sheen that feels super soft and smooth against the skin. Sateen is naturally wrinkle-resistant, and its sheen will diminish with washing and use. Recommended if... You’re seeking a sumptuously smooth feel – but without the shiny look of silk. If you have sensitive skin or just love the cool touch of cotton against your body. You want to avoid all the nasty chemicals they use in non-organic cotton production.
