Why should you wear an Arctic Cool Double Layer Headband? Not only do our headbands keep your sweat and hair out of your eyes while you're pushing the limits, the Arctic Cool Double Layer Headband keeps you cooler, longer thanks to HydroFreeze X Technology. When you begin to sweat, or the headband gets wet, HydroFreeze X Technology automatically activates and wicks moisture away from your forehead, causing a cooling sensation. Plus, silicone beads on the inside of the headband keep it in place, so it will not slip down. Look cool, stay cool with an Arctic Cool Double Layer Headband! Adjustable and durable. Reflective printing for increased visibility/night safety. Lightweight and breathable. Antimicrobial.
