Keep more comfortable when running in cooler weather with the On Running Core Headband. Made with recycled polyamide, the soft and cosy brushed lining keeps your ears and forehead toasty while letting excess heat and moisture escape. The quick-drying material also ensures comfort and quick turnaround times after washing. With a snug fit, there's no need to make mid-run adjustments and a reflective logo makes you easier to spot during early morning or late evening workouts.
