I have tried SO many headbands to work out in over the years, and they always seem to slip off. Even if I use bobby pins to secure them in usually, they still slide off. I decided to try Sweaty Bands after reading a review on an online forum for my gym, and WOW I will never try another headband again. These actually stay on my head the entire workout, are super simple, AND really cute. I will definitely be purchasing more in the future. 10/10!
