If you like thin headbands, you’ve found the only ones you will ever need to purchase. These are my go to head bands. One pack usually lasts me a year and I’ve used them for as long as I can remember. I order a new pack every year because I wear them so often that they stretch out, they get dirty, or I lose them just out of human nature. They have a great jelly band on the inside that keeps them in place no matter what you’re doing. I use them for working out, everyday wear, and for days of marching band camp where I am working 12 hour days and rarely have to readjust them.
