Soft and comfortable, this 100% cotton bed linen is made using an innovative spinning technique that helps you maintain an even body temperature. 100% Cotton The world's most widely used natural fibre, versatile cotton makes the perfect bed linen cool, lightweight, soft and breathable. 400 Thread count This number refers to the number of threads per square inch. Typically, the higher the thread count, the softer and smoother the feel. Temperature balancing This Hygro technology bed linen is made using high-quality cotton, specially spun to create a hollow core that traps air and wicks away moisture, helping maintain an even, comfortable sleeping temperature. We recommend washing this bed linen at 40ºC but it can be washed at 30ºC. Lower temperatures save energy, helping to be kinder to the environment.Worth knowing: Duvet covers and pillowcases are available to purchase separately, and not in sets.
