Whether you’re headed out for an evening rock-climbing session or a pre-dawn run, the BioLite HeadLamp 330 Rechargeable Head Light will stay in place and offer full visibility. Featuring the proprietary 3D SlimFit Construction of BioLite, this lightweight headlight secures on your head even during intense activity. This means you won’t deal with a pesky stretched-out strap or a light that falls in front of your eyes. On top of that, the light itself is only nine millimeters deep. As a result, it appears practically flush with your forehead and won’t impede your sight. When used on low strength, the light lasts 40 hours—enough time to see you through most outdoor activities. This no-bounce rechargeable headlight shows you how much battery life is left so you have plenty of notice before needing to recharge.
