After having done some research about bamboo based fibres, I have concluded that there is really no benefit to buying bamboo sheets besides the fact that the resource is eco-friendly and renewable. The actual fibres themselves undergo so much chemical breakdown to be made into the rayon that all of their holistic properties are lost during the process. HOWEVER. These sheets are super soft and comfortable, they are breathable and I love the deep pockets, which fit perfectly on my 22" deep mattress. Finding sheets that won't slip off is awesome! I'd definitely buy these again. The only downer is that they wrinkle very easily.
