A headlamp so comfortable, you'll forget you're wearing it. The Biolite 425 rechargeable headlamp offers 425 lumens of brightness power, 5 front lightning modes and 2 rear modes, a customizable fit and USB rechargeability so you can leave the disposable batteries behind. The moisture-wicking technical fabric of the headband is ready to handle any activity, from your night runs to your deep forest escapades on rainy days. Be seen from the front and the back with the rear red light, making sure you are visible from all angles, even in low light conditions. The weight distribution and the 3D SlimFit construction gives you a weightless feel and helps the lamp to sit flat on your forehead. It's time to try a headlamp you'll keep on your head and not around your neck.
