Review on 🏋️ EasYoung Non Slip Headbands - 6-Pack for Men and Women. Sweat Wicking Elastic Headbands for Sports, Fitness, Yoga and Running. Unisex. by Bobby Martinez

Reviewer from Houston, Texas (read: high temp and humidity) and has been using it for about 6 months now. The material is thin, silky, soft and pleasant to the touch. I have an 8 1/2 head and it doesn't feel tight. They work best when the humidity is < 80% and you can hold your head up straight. They're still good in higher humidity if you can keep your head up while running etc. Then sweat is directed to the back of the head (or where the band is lowest). For example, if you have to pull weeds around the house with your head down or work on all sorts of things and drench the strip, then it drips from your forehead. Glasses are no fun. In such cases, thick cotton tapes will last longer. If you carry several of these straps in your bag, they can of course be easily exchanged if necessary.
