When I opened the package, the sheets felt slippery--kind of like a thicker satin material. I washed them and their consistency didn't change. I put them on the bed and have slept on them a few nights. They're just the perfect weight, a lovely color, conform to my body (not stiff but very soft). These sheets remind me a great deal of satin. However, after some quick research, I learned that the process to make sheets from bamboo usually removes all the bamboo, leaving rayon fabric that is heavily treated wtih chemicals. So while these are comfy, I'll do more digging before I buy more.
