When it comes to sport, headwear is like shoes and t-shirts: you can never have too many options. The On/Off Headband hides carefully thought-out properties in a small, lightweight package to make sure you stay cool and clear-headed in all situations. The stretchy, seamless fabric is designed for ultra-effective thermoregulation and comfort during training and racing. The on/off technology offers all-round ventilation for rapid evacuation of perspiration. It dries up to 7 times faster than traditional headbands to ensure your head remains fresh in hot conditions. The ultra-soft fibres fit the contours of your head and ears without creating uncomfortable pressure points, keeping eyes and forehead free of sweat and unruly hair.
