There's no getting around it: When you run, you sweat — sometimes a lot — and a headband is a simple way to keep all that perspiration out of your face (and it can keep your hair out of the way, too). The best men's headbands for running are lightweight, moisture-wicking, and secure enough to stay on your head without sliding down. Here's why these features are important:
Lightweight design: When you're running, you don't want a headband that feels thick or heavy, especially if you're sweating hard. Even if you're training in cold weather, the material should be soft, lightweight and unobtrusive.
Moisture-wicking fabric: The whole point of a running headband is to absorb sweat and prevent it from trickling down your face. That means that the material needs to be highly moisture-wicking, pulling sweat away from your skin and moving it to the outer layer of the headband where it can dry more quickly. Polyester and nylon are two materials that are especially great for this.
Secure fit: There's nothing more annoying than having to readjust your headband every five minutes to keep it from sliding down your forehead. The best running headbands feature stretchy spandex in the fabric blend or an elastic band to help it stay in place.
Another thing to consider when shopping around is the width of the headband. Wider bands often do a better job of keeping longer, thicker hair out of your face, so keep that in mind when making your selection.
