Once you have spent a night between the bamboo sheets, you will not go back to any other bed linen. The 400 thread count Cloud 9 Bamboo fabric is silky soft and has a lustrous finish that gives a beautiful silky feel and soft drape. These sheets are anti bacterial where the Bamboo's natural anti-microbial agent 'Bamboo Kuhn' prevents the formation of bacteria. They are also hypoallergenic which means that they are dust and mite resistant making them suitable for those with sensitive skin. They also have a thermal regulating feature where the Bamboo is 4 times more absorbent than cotton, so that it is cooler in summer and also has the effect of trapping heat to keep you warmer in winter.
