Details 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 flat sheet in Pink Clay. 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.
