Not the worst. Not the best.

First off there is no terry cloth headband like it says in the description. I know the reviews said there isn't but I wrongly guessed that was an older batch. They still don't match the description. There is nothing to prevent sweat dripping down your forehead. Nothing.

The material will NOT soak up and hold sweat. As a synthetic material it will do a great job of pulling sweat off your head and letting it dry quickly. But for the forehead sweat that's heavy, it won't wick away the moisture fast enough.

The material is a little thin to be used as a sun screen for bald guys. It'll help but not be a great all day solution. I think you'd still get burned through these.

And the material is very flimsy. It's hard to tie one on your head, remove it, and put it back on without retying it like you can with a banana.

All in all I was just really unimpressed by these and returned them.
