Made from 100% flax linen. Breathable 170 GSM fabrication. OEKO-TEX® certified (so, no nasty chemicals). Make your bed look as good as it feels with our 100% French flax linen duvet cover in Sage. Complete with button closures to keep your insert nice and snug, this duvet cover is as easy to care for as it is to sleep in. The thing about linen is it only gets better over time; the more you use and wash it, the softer and more comfortable it gets. What’s more, linen is good for you too: it’s anti-static, anti-bacterial and naturally temperature-regulating, meaning your cover will keep you cool in summer and cozy in winter.
