When it comes to sport, headwear is like shoes and t-shirts: you can never have too many options. The trail running 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. The clean white design can be worn as is for a stylish look or under a helmet, a headtorch or a hood for extra freshness. If you look closely, you will notice the ventilation holes even spell the brand name for a special touch.
