2c with 2a &b mixed in, normal fine, normal thin, porousI get "meh" results with my sleep cap. Mine looks nothing like the photo. Mine is looks more like the do-rags or wave caps. Maybe that's the problem, I don't know. But It seems to smash my hair into an odd pancake shape and it's not very comfortable to wear overnight. I have a tendency to take it off in my sleep.
