With the BioLite rechargeable head torch you get the best light performance and an unparalleled fit. Thanks to the 3D Slim Fit construction, the head torch is thin enough that you will never be bothered by it sliding off or bouncing around on your head. You carry the battery on the back of your head. Two beam patterns (broad or narrow), a red LED light and a strobe-mode make this the perfect head torch for outdoor activities such as mountain climbing, running or backpacking. The narrow beam reaches quite a distance, which is perfect when you're trying to find your way. The broad beam is nice for up close. For example, reading a map.
