New in bag. Made from 100% flax linen. Breathable 170 GSM fabrication. OEKO-TEX® certified (so, no nasty chemicals). Ultra soft and incredibly durable, our 100% French flax linen flat sheet in Mineral is a versatile addition to your collection. Generously sized to just graze the floor, these sheets serve as lightweight covers on their own, or as a luxurious extra layer alongside other linen pieces. 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.
