These tie headbands are seriously versatile - whether you're into karate, yoga, running, or just need something to keep hair and sweat out of your face during workouts. The tie design is genius because it's fully adjustable to fit any head size comfortably without that tight, squeezing feeling some elastic headbands give you. Made from 92% polyester and 8% spandex, they're super soft against your skin while being stretchy enough to stay put. The moisture-wicking fabric actually works too - it pulls sweat away from your forehead so you're not constantly wiping your face during intense activities. At 2.4 inches wide and 39 inches long, they provide good coverage without being bulky. You get two colors in the pack - black and red - so you can mix and match or share with a friend. The stitching is really well done with reinforced edges, so these aren't going to fall apart after a few washes. Beyond sports, they're great for bad hair days, as costume accessories, or just keeping cool during hot weather.
