I'm really delighted with this buff. I'd never heard of them a month or so ago but someone directed me to a youtube video demonstrating their use and I was really impressed (https://www.youtube.com/watch?v=ewVEK-AElDY). Since I've started using it, it has lived up to expectations. Mostly I wear it as in the picture so that the flappy bit protects my neck from sunburn (I know there hasn't been much danger of that so far this year, but better safe than sorry). The magic fabric is great for wicking the sweat away - I've worn it on 15 mile runs and the wicking/evaporation has been mega effective. Also, on those days when you're not sure whether you'll need a hat (either to protect from sunburn or cold winds) it's so easy to just scrunch it up in your pocket in readiness.
If you cover your hair/head but not your bangs/fringe, then this could be a good option. Unless you have really long/ thick hair, you will be able to wear it and just twist and tuck in at the back. V. handy
