I have three of these and love them! I have very fine short hair and they stay put. I wear them to Jazzercise and have no problem. I prefer the thin ones because my hair is so thin. Several of the instructors put their hair in a ponytail and then use the sweaty bands to keep any stragglers off their face.

My Jazzercise location puts in orders on a regular basis. The price I paid for the ones I ordered through the class was significantly less than the website. You can find them in the stores listed; however, the selection tends to be very limited. I bought one from the running store and they only had about 4 to choose from.

The backs of the bands are made of a velvet material which keeps them from slipping. I have one with a white background that gets pretty grungy looking but I just throw it in the washer.
