The Petzl Nao headlamp makes it easier to cast hands-free light on everything from deep caves to dark basements. The USB-rechargeable headlamp reads ambient and reflected light, adjusting its beam accordingly so you don't have to keep tweaking its brightness when looking from map to trail, or toolbox to the task at hand.
