Mesh Cap instead of straps

Has anyone tried the mesh caps available on various sites instead of the straps for the standard masks? Seems like it would be a great alternative for us ladies to messing up our hair everynight and having bad cases of "bed head" every morning.

I was worried about my hair at first,but I find that it isn't much worse than the pillow head I would usually have in the mornings.
I usually sleep on my stomach,so I don't like it when I switch to back sleeping because that really messes up the back of my hair.
I hadn't heard about the mesh caps.Haven't looked "around" yet on the sites.
Good luck
