I am Very Picky about sheets. I like cool and crisp sheets, mostly percale. I've tried many types of sheets, including bamboo. And I haven't liked most of them. I Love these sheets. Most percales (my preference) are thin so tear easily and don't wear well. These sheets, though not percale, are Very Comfy, sturdy, kind of silky. I can't speak for the Nanotex. I can say I am ordering another set of these sheets, and I Never do that.
